Become outcome independent.
E.g.
Today im going to go to this event and do my best to practise X skill. The only thing that matters is that I try to practise it. It doesnt matter if it works or if it doesnt.
And others have said, don't limit yourself. If you go to practise getting deep into people's interests and it ends up working well with a cute girl - ask her out. Because you are outcome independent, it doesnt matter what happens. You still practised the skill you set out to. If she says no, play it off like it was no big deal and you can still be friends if you are trying to expand your social circle.
Even with friends, you want them to think of you as someone who is capable to get girls, so if you ask them out and then end up as just friends, it's still better than going straight to just friends.
