How can one overcome his inferiority complex?

I beleive that overcoming an inferiority complex is about self talk. If you tell yourself in your head that you are not good enough you will miss many fantastic opportunities. After all you are the only one that sets your benchmarks so therefore only you can say if you're good enough. If you beleive you are good at something you will do better at it as research has shown. so to overcome the feeling of inferiority you need to tell yourself over and over again your strong points and what you can acheive rather than what you can't.
