I definitely agree that the lack of self confidence is holding a lot of people back from achieving their goals, and I respect your opinions. However, I personally don't think that it's that simple to achieve true self worth and a lasting self esteem. It definitely wasn't for me. I had to do a lot of inner work, which included meditating, gaining self respect, becoming more grounded with how the world works, and gaining self awareness and a lot of self discipline. I found the roots of my lack of self-confidence, and worked through them. Personally, I believe this to be the best way to develop lasting self-confidence and emotional security.
