For me, a career change seems drastic and unnecessary. If you want to do work with your hands, pick up a hobby that lets you do that, and use your finance salary to fund it. If you want to be traveling all the time, find a high-paying sales job that lets you work from the road to financially support all that travel. If you want to do good for the world, volunteer--but keep doing the uninspiring pointless work to support yourself. You're probably going to see a lot of survivor bias in the replies here--nobody ever wants to talk about how they burned out, tried becoming a janitor or whatever and failed and went broke.
