You nailed the top 2.

Marmaris, it’s a beautiful beach town

I pay a CPA in my home country (USA) to handle my taxes for me.

Success in making friends or romantic partners that match my lifestyle.

Meeting people in the gym lead to gym friendships and girlfriends that prefer to exercise/be healthy than party.

Meeting people in cafes/coworking locations lead to coworking friendships and groups of entrepreneurs.

Dating apps where I strictly look for partners that don’t drink/party/drugs lead to exactly that (the adventure/explorative type of relationship).

Libraries may be the best (if you like to read). Striking up a conversation with a nice person over what type of books they read is very fun! I’ve gone on coffee/tea dates to discuss books with women I’ve met at the library.

Dating apps, gyms, libraries, coffee shops, parks. I agree with you it is difficult, but I’ve had success in the aforementioned.
