Six F Words
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 - doing what they're good at and what's needed in the world.
