Going to push back a little here. The two of you are miles ahead of most of the world (and your own country) in income and education. You'll be able to retire likely decades before the rest of us slobs. In the meantime, find some awesome hobbies, you can certainly afford it. Learn some fun and difficult shit, get really good at it, rinse and repeat. Your job doesn't have to have meaning, just enjoy your life; you're set up to enjoy it a lot more than most. If you can't find any fulfillment outside of work, then good luck.
