The biggest mistake newbies make is just not keeping at it. Every 6 months I see new guys enter the local PUA community at meets and a bunch drop out.

Some of them just wanted to find a girlfriend, who is alright if that's your goal. Or just gave up because they found this too hard.

So bottom line just keep going out and everything will figure itself out to your own style. No amount of watching videos is a replacement for logging in the man hours in the field.
