If you can’t do it atleast have a hope. Don’t get disappointed because that makes you go into deep depression. Take a moment to analyse yourself. Take a deep breath and have a moment to revise what gone wrong.
If you didn’t get what you want then definitely something more is waiting for you. You have to wait for the moment and be patient till then. You never know what’s next. If you know what’s gonna happen then life becomes so boring. Be brave enough to accept the failure. Success don’t teach you because failure make you think in all possible ways.
Believe in you and there will be some power deep inside which pushes you to do something that you never thought of doing. Believe while you live and make it worth.
