I am a high-powered individual being busy with self-improvement, getting great jobs and doing a start-up as well. Due to a rocky childhood I still drag with me some anxiety, and often I can rationalise it away but it takes a lot of effort and feeling all tight until that happens.

I am looking for a long-term plan to eliminate this anxiety (not a sudden fix as I know it does not exist). I need to be able to go from failure to failure without much problem, or I will never become the individual I want to. I do not really know what constitutes this plan, other than meditating and stuff like that.

Advice is appreciated.
