Funny, I've been asking high productive, independent people this question lately, "how do you choose between the vast number of options, projects, hobbies, places to live, and so on?"
In terms of big choices like where am i going to live or what work am I going to do be doing the next X years, I think the most important key is to do something you genuinely enjoy doing. Not because you'll make money "one day", will look good to your friends, or whatever. Hobbies are different. You can toy around with poker, gardening, or whatever on the side if you want.
The second most important thing is just do shit. I'm a pretty indecisive person with a lot of interests and freedom to pursue them. So, I just do whatever seems the most accessible and important in the moment whether or not I'm 100% sure it's what I want to do or should be doing.
For example, I was living in Boston and having a great time. Getting high productive work done. A lot of my best friends nearby. But I left to go travel cross country in a RV because...I had a RV and I always wanted to do that. Now, I'm pretty sure I don't need to do this ever again. But if I had stayed at home, I would be constantly wondering if I should do it or not. (note i am in no way endorsing the idea of traveling cross country in a RV).
So, either do what you want to do. Or just do whatever's on your list. Either way, you will only figure it out by doing stuff. At the very least you can cross things off your list that you're sure you don't want to do. No book, person, or blog post can replace experience. It's kind of the same principle in pickup, just approach. Whatever happens afterwards, you'll quickly learn what matters and doesn't.
