If you are crap at Day Game then the answer is to start having go sir. It's tough, but remember when starting Gaming full stop was tough. Like you I rarely find girls that excite me in Night Game so had to start Day Game.

A good tip is to start off slowly and get your bearings with strangers on the streets. You need to start realising how friendly guarded unfriendly looking strangers actually are. So, start by asking girls, or failing that anyone, for directions. As you go along you can lengthen the interactions and start to step up things.
