Back and front

Back and Front, Front and Back My steps gradually make Taking me to a land With success, where I stand. Being stagnant , oh I fear Rooted to the ground there, Because moving is life Sometimes comfort and sometimes strive. Oh leg, don’t take pride- “I am ahead of my silly twin behind.” Like each day turning night, There’s a decline to every might. But cry not on fall Because standing later is success afterall.


The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's gravity. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By volume, dry air contains 78.09% nitrogen, 20.95% oxygen,[2] 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air content and atmospheric pressure vary at different layers, and air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in Earth's troposphere and in artificial atmospheres. The atmosphere has a mass of about 5.15×1018 kg,[3] three-quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space. The Kármán line, at 100 km (62 mi), or 1.57% of Earth's radius, is often used as the border between the atmosphere and outer space. Atmospheric effects become noticeable during atmospheric reentry of spacecraft at an altitude of around 120 km (75 mi). Several layers can be distinguished in the atmosphere, based on characteristics such as temperature and composition.

An appeal

Stop oh man, Don’t red your hand With the innocent blood that flows In your body like of those Whom you have shut still, Only for your mad will. Who will never return to their own People ,like you have, back at home.   Peep into the eyes Of the body that lies Still on the ground, Like millions around. Let their motionless heart Bring the human apart, From the clutches of ignorance That for your good, is a fence.   The good resides in you. Just be one of the few Who hold its hand And come out of the dark, eerie land. Let my words  not win an award, But your changed hearts, be its reward. Because, The words are of vain, The world will be the same , Till your deadly guns turn lame.

E-Retail Bubble: Reality or Myth?

A bubble occurs when an asset is valued more than it really stands. Maybe that is the reason e-retail is seen as a bubble by few. There are a couple of reasons for this over-valuation. E-commerce is preferred because of convenience, range, and price it offers. This requires a lot of investment in necessary technology, procurement, and operations. India has not seen a commerce revolution like the USA did in the late sixties and the seventies when retail chains such as Walmart started. They made the ground for e-commerce boom in the west. In India Big-bazaar, V-mart etc. have started recently and have not been able to transform the logistics problems in the country. About 80 to 85 percent of the logistics are still unorganized in India, thus the e-retail companies have to invest heavily to upgrade the logistics and operations infrastructure. As a result of this, the e-retail companies in India bleed cash for long, making the profits smaller. Secondly, Indians are yet to trust e-commerce completely, which can be seen from the fact that more than 70% payments are done by “Cash on Delivery” and approximately 20 percent of the orders are returned. This might be because of less knowledge of technology, network penetration, security concerns etc. Whatever is the reason but it shows our trust issues with the e-business. But the same facts also suggest, there is a huge scope for growth in the business with time when the infrastructure develops and people are more well off and prosperous. In summary, e-retail is still in its nascent phase in India. Surely, many e-retail companies are yet to make a profit but they are still thriving as they serve human needs. There is a huge scope of growth though it faces few hurdles at the present. Therefore calling it a bubble would be too early.

Operation You: Taking Personal Responsibility

There’s just no easy way to say this: your biggest problem is you. It’s not the weather, or the economy, or the government, or the alignment of the stars. It’s you. Phew! I’m glad we’ve sorted that out. Now, we can start getting you out of your own way. Prepare yourself for Operation: You. The Stuff That Happens TO You vs. BECAUSE of You In life, there’s stuff that happens to you and stuff that happens because of you. One you have control of, the other you don’t. The stuff that happens to you is often out of your control. Your boss is in a bad mood. Your football team got beaten in the playoffs. Your car won’t start. Many of these things you cannot control. Perhaps you can influence them. For example, servicing your car regularly means it probably will start, but largely that stuff just happens. If you put too much effort into worrying about it you’ll waste the energy you could actually use to effect some positive change in your life. The stuff that happens because of you and your actions is completely in your control. In understanding this, you put the power in your own hands and remove it from those around you. Meaning, no one else can prevent you from getting what you want. And that’s why I wrote earlier that you have to get out of your own way. Are You at the Cause or the Effect? Psychology students are taught about external and internal loci of control. An external locus of control is when you believe external factors control your situation. While an internal locus of control is when you believe you are in control. An internal locus of control sees you taking responsibility for what is happening in your life. The key is personal responsibility. When you take responsibility for what is happening in your life, then you put yourself in a position of power. You put yourself in a position from which you can achieve your dreams. NLP practitioners learn about cause and effect. When you are in control, you are at cause — you cause your results. When you are at effect, the external world affects your outcomes. Understanding the differences between these two positions is essential. Cause is a position of empowerment. Effect is disempowering. The position of effect allows you to explain away your poor outcomes. Cause doesn’t let you off the hook. If you want positive outcomes in your life, you have to be responsible and in control of your responses, actions, and outcomes.

I Fear

I m scared that happiness born,  Someday suddenly would worn Rooting me still on the ground With helplessness around. Imaginations would die Crushing me to cry. Someday suddenly you would strive, Leaving me dead but alive.  I am scared that my eyes would Struggle to see you stood,  Near and Nearer to me More than I dreamt to be. I would walk but be standing inside, Still there where my life died. Someday suddenly you would strive , Leaving me dead but alive.
