Try as many things as you can, seriously try them. The things you like go back for more. School is actually pretty good at doing this, modulo teacher quality.

Try as many things as you can, seriously try them. The things you like go back for more. School is actually pretty good at doing this, modulo teacher quality. Then, in the course of living your life you may find that you've discovered something new. This is very rare. More often your identity becomes a unique combination of preferences across a (surprisingly short) list of trade-offs in your field. Then again, finding something new is as much a burden as a blessing, so you can reasonably count yourself lucky if you do discover something AND if you don't. Remember that as a technologist you have an inherent amplifier to your ideas, and so it's good you're being careful here. One thing I would recommend is selecting an "Enough Number", which is the amount of money that would be enough for you to earn in your lifetime, and you should make a solemn vow to give away anything above and beyond that, or even better, resign and let others have a chance to earn wealth. Good luck! And may you discover a way to help yourself and others in the best possible way!
