Three things i Have learned in my life. 

First is
NEVER GIVE UP:
Never give up hope work hard for ur goals.This world will try its 
level best to make u same as She is ...careless but u need to hangup 
because u are u and u r different than everyone.

Second is
TRUST:
Trust is the core ingredient for any kind of relationship 
whether its between a father & son or between two friends.
There is no way a relationship can stand if there is no trust.

And the Third is 
BELIEVE ON ALLAH: 
It is the most important of All .Believe in the existence 
of Allah in ur heart in ur soul. believe on HIS powers and trust HIm 
for every work You Peform.
