If you read the sidebar, as well as some brilliant posts, and start implementing what you've learnt, you'll be well on your way to a successful life as a man. However, a lot of men find it difficult to break away from their computer screen and actually start working towards their future as a better man. I have read, and agree, that a large reason for this comes from the fact that humans used to live in small communities, and that our brains evolved to worry about what others thought so we wouldn't be outcasted from the group.
If you find it difficult to randomly approach women on the street or in clubs/bars, or if you find it difficult to be rejected by people or to voice your opinion then it could be because somewhere in your mind, either consciously or subconsciously, you are worried that other people will find out and that it will get back to you or your group of friends and you'll be outcasted from the group. While we know this is a load of shit because of the pure size of the population these days, the thoughts still remain.
A solution which helped me is to drive, get a bus, get a train, whatever and just go. Go as far away as you can until you remove any uncertainty about whether or not this will get back to you. Go somewhere that you will never have to go again in your life if you don't want to. You won't have to go far, maybe 10-20 miles max, until you find a community in which you can feel confident that you can approach women and practice what you have learnt and it won't get back to you.
Once you get there, start approaching, start getting rejected, start voicing your opinion, it doesn't matter because no one you care about will know. Do this as many times as you like, and as often as you like. Once you feel more confident and see results, you can start implementing what you have learnt in your home town.
