I have huge insecurity about my intelligence, whenever I see smarter people it stings and I loose focus in pursuing my goals even though I am hard working. Please help?

There's no simple "answer" to this, and really it is worth speaking to a specialist who can help you with these self esteem issues.

Personally though, I find it helps if you ignore what other people are doing, and set yourself personal targets of things you want to achieve.

This way, you have something to aim for, once you attain it - hen you'll get a boost of confidence, and before you know it, you'll feel like an equal to everyone else - if not smarter!
