FWIW I see a lot of similarities in our lives and outlook. I too have had introvert problems, and still struggle with it in some situations. I have had some success seeing a self-esteem C. Also, you can actually learn a lot by studying the arts of seduction and how pick up artists work. A lot of that stuff is easily tailorable (is that a word?) to social situations in which you're not actually trying to pick up a date for the night, because the same things that attract women in clubs will attract people to want to interact with you in social situations. Just some thoughts.
