Negative past experience teach you how to be better for the next one, we learn best from failures and they shape us for the positive if you look for the silver lining. I still have doubts about myself everyday but find a way to push thru and end up surprising myself and you will too, it doesn't come naturally, you have to work at it and overcome your fears. Take one step at a time and one day you will look back and be proud of how far you have come. Cheers! xox
