I don't like the word 'game' but I couldn't find a better way to describe it. So this is my case:

I really have zero troubles with talking to girls, some kino escalation, some flirting, just having fun in general at parties and large social events. Probably I describe this a little bit exaggerated, I'm not so good at this all yet, but I'm content with how everything goes at parties. By the way, I don't drink, so it isn't the alcohol that's helping me there - just the fact that it's pretty normal there to flirt with girls I guess.

The problem is that I'm a little bit of a different person when it comes to daily situations like stores, busses, just the street in general. I find it much harder to start talking. So I'm not content at all with how I am on that terrain and want to expand what I do at parties to my daily life.

The advice is probably obious: just start doing it. But I've repeated this many times in my head without many results. Could Seddit give me some more advice on this matter. Thanks!
