One of the major points in mystery method is that a PUA should
NOT require the supplement of alcohol to achieve a pick up.
If you want to start getting it right without alcohol in you (or the girls) it will be like starting all over again. and it will be frustrating.
getting started: watch some of mystery's seminars - i found them to be a huge help.
as charlie0 said. get out during the day.
start with openers. move on to number closes, instant dates etc.
this will develop your confidence, ability to hold a conversation etc and soon enough you'll be able to F close completely sober girls
