Because we are only humans.

And maybe this life already has plans for making a sane go insane. It is just a matter of time before one can truly confined  to the fact that somewhere there is a rainbow..somewhere there is a silver-lining..and that somewhere you need to get lost just to get a better hold of yourself. Until then, we struggle, we bleed, we cry, we lose faith, we doubt, we fall down, we get bruises and wounds , we get stabbed , we become a clown and we die a million times before our actual death.

We are reminded of the fact that its a tough world out there, you will not always be your parents little angel. Its time you walk out from your  comfort zone and embrace the worldly winds on your chest. Its time to grow up, be responsible, be bold and be able. We thrive to be the best among the best. We thrive to beat the very next person. We thrive to show no mercy to anyone. We thrive to prove to the world that you are something. In all these life's chaos and nonsense rituals of everyday , you tend to forget who you are actually. 

You miss out a lot in life. An orphan knows he is an orphan only when he sees his friends coming along with their parents. you know you are sad, when you see bunch of people laughing together. Its like you miss out so many  good stuffs. Its like you are scared to go against the flow of life. Its like you wanna be in a safer side, by going with the flow of life.
Its like you are on a race, and because everyone is running, you are also running without knowing the reason "why,how and  what for,??" Its okay to be scared actually, its okay to question about life and its purposes, its okay to be the odd one, its okay to take one thing at a time, its okay to fall down, its okay to just do things that are classified as "insane" things. Its okay to feel different. Nobody learns lessons of life in a easy way, its always the hard way. Not that you can always wish for a smooth journey, sometimes there ought to be some bumpy rides. Bumpy rides that can prepare you for the worst. Sometimes you gotta risk, gamble your life, your heart because through this only you become wiser.  After all life is once, don't be afaird to make choices, don't be affaird to learn from mistakes, just don't be. Learn, let live and get the best out of it . You have got your own charm that nobody can dare to question, do random things, be crazy, break some rules, don't be a "society-based-person", be yourself, fall in love, experience heartbreaks, flunk in exams, bunk classes, drink beer, take life lightly, don't be hard on yourself, listen to others but follow your heart. Be different ....be you....
Cheers.
