A few years ago, a wise man
was giving me some career advice. He gave me a list of six F words: fun, family, fame, fortune, freedom, and force. In life, one can only have two of them. For example, college professors (except for ones trying to get tenured at top universities) take family and freedom. Artist takes fun and freedom. Politicians take fame and force. People who do startups take fortune and fame at a very high risk and maybe some fun until the money starts to run out.
I think it's a good way to frame things. Once you know what you want, it's easy to pick a career or a lifestyle. But if you're not honest, life will seem like a square room with a rectangular rug. It will never feel right.
Another good advice is to do something at the intersection of what you enjoy, what you're good at, and what's useful in the world. Otherwise, you will hate your work, suck at it, or not find a job. People who want to be artists always struggle with this. The world needs very few of them. So most of them struggle with the last two.
