For a long time I have been withdrawn had lot of personal problems from my childhood (I am now 23) and was never that confident with life and myself. The last week or so women have been starting to show an interest, I don't understand why is this? Have I changed?
I think (generally) women are attracted to men who appear confident. Whether they really are (inside) or not doesn't matter (per se). In your situation, it shows and the evidence is clear. I'd say, enjoy!
Pretending confidence is the same as confidence practice, right? Practice makes perfect is what I have always heard. Keep it up, then it will be 2nd nature.
