Whatever negative things people think and say about you is enough to bring you down provided you belief that it carries a weight that can push you hard. Don't agree to accept what critics say; be prepared to silence them by doing what they think you can't do!
Most of the world’s problems are caused by people who made education compulsory, but personal development optional. Because of them, we have many intelligent people who lack good characters.
Education is not merely meant for you to write and pass exams, get a good job and a good spouse, and settle down for survival.
Make your education valuable. Apply what you learnt. Refuse to take the back seat and watch things happen. Join the change and be part of the change.

If don’t want to be eliminated, you must be innovative. Update your knowledge and you won’t be outmoded.
