I never did the things you mentioned either (except for travelling alone - it's very difficult for me to travel with other people due to having very different needs) and I do have a partner, we met online a few years ago.
I'm older than you so don't worry, there will always be time to meet someone
nowadays people meet potential partners at any age, someone in my family remarried in their late 50s. We don't need to find someone before we're 30 anymore, these times are over. We live longer and have more possibilities.
BTW my partner did all the things you mentioned (partying, having a lot of friends and so on) but didn't meet a partner this way.
But I would like to ask you a question: do you want a "typical" life because that's what you really and deeply want in your heart, or because you feel like you "should" live like everyone else?
