Having lived life uptill now(by the grace and mercy of Almighty)...i've learnt and realized some important things-
1)you are your best friend
2)you are your greatest enemy
3)you are your biggest motivator
4)you are your greatest discourager
5)there's no such thing as a free lunch in this world
6)never underestimate the capacity of other people to let you down
7)hear out what others have to say even if you don't concur with their views
8)your hardwork and patience both will be rewarded someday
9)trust only 2 people-Almighty and yourself(if you're lucky..you'll get a few more people in this department)
10)confront your enemies but avoid them when you can
11)be open to change
12)do things that make you happy
13)live like it's the last day of your life
14)love like there's no tomorrow
15)And lastly remember..you don't have to prove yourself to anyone..be confident,have self belief and just do your thing.
