There are those who would argue doing anything is better than doing nothing while you try to figure out what to do. I'm in a position where I know what my passions are and am sufficiently constrained by resources that I can't afford major mistakes; but if I were sufficiently wealthy and indifferent, throwing darts at a board with a couple of ideas on it and just doing whatever has a certain romance to it.

Don't do nothing while figuring out what to do. But you should still spend time thinking about what to do.

If you're wealthy time and personal energy are the most valuable, irreplaceable resources you now possess. Why squander them on fruitless, random pursuits if you could think strategically and do something that really matters?
