How good is ego?
A healthy dose is always worth it. It makes you trust yourself to do what you want and in the way you want it.
With too much ego, you could end up losing things which you wished you still had.
With the right amount, Nothing is going to stop you.
Believing that you are one of the best to do what you do certainly helps.
Signing off with lines inspired from the movie Ghajini-
Theres a thin line between self confidence and vanity, I CAN DO IT is confidence, ONLY I CAN DO IT is pride.
