BELIEVE!!
Had I known was all they kept screaming,when nature demands caused unexpected tears,unrisen stars and failures.
Lot of people fade into thin air, they tend to lose their well-sighted visions. Glorious kids,stars untold vanished unheard and unnoticed, not that they are not aware of the potential they have got, not that they are being blindfolded to see the treasures deposited inside of them.
Well, the main drawback to this is UNBELIEF. Visions which can explode into greatness are cut short by ignorance of unbelief. Something can be done but hopelessness got them on the other hand, thinking there is no way they can do anything.

There are many causes to this, but I want to talk about just one point which is what I call FREE- RADICAL
Scientifically, free-radical is an atom or group of atoms that has an electron that is not part of a pair, causing it to take part easily in chemical reactions. free-radicals cause diseases such as cancer in the body. How does this relates with the title? So many were ambitious, having great minds but they've been made stagnant by everything surrounding them. Friends, family have become factors of their downfall, Oops, did I just say downfall? Did they rise for once? No they didn't, the kind of minds we associate with determine how high we are going to fly. Like I have said, friends can become free radicals in one's life, even family, they won't give you any reason to excel, free radicals do not believe there is something like taking risk, they are satisfied where they are. All they say is they are going to make it big without making any move, some have background issues but forgot there is a saying that your background shouldn't lay your back on the ground..... Stand up, wake from your slum, eradicate all free radicals then take a risk. Failure brings hope of bright beginning, there is nothing called easy in life. Ask most of the richest men where they were thirty years back, they would tell you it wasn't easy, perseverance took them to where they are today..
Free radicals pervert peoples mind from becoming great. One of my tutors always talk about a quote which says "you cannot feature in the future you did not picture" that's true but after you picture anything, take a step, take risk and stop pettifogging. You can make it if you want, be yourself,don't compromise. Bring out your inner beauty, then you'll make it. Say no to free-radicals and believe.
