''its always seem impossible until it is done'' - Nelson Mandela

"Whenever you feel down, just remember how badly you want it at first place"

Everything that happens in life is neither good nor bad. It just depends on your perspective. 

And no matter how it turns out, it always ends up just the way it should. Either you succeed or you learn something. 

So stay positive, appreciate the pleasant outcomes, and learn from the rest. Your positivity will rub off on everyone around you. :)
