Sundar gave a little insight on how a person can have his / her dreams fulfilled. The key factors of success that he mentioned- while addressing to the gathering are as follows:-
Take risks and keep trying until things start to work out in the long run.
Think big and try to do something that excites you and even if it fails, wear it as a badge of honor. Further, try it again.
Work with people who make you feel insecure, they are the people who are better than you, if you feel very secure in what you do and you are comfortable with it that means you are not pushing yourself, pushing to the limits is a crucial part of learning.
