I switched to a job that gives me more free time, can't be happier. Money past a comfortable level (enough for food, living and some savings) clearly can't buy not having to run around everywhere and think about your next move all the time. I've seen so many people regretting they spent their life just for their job(s) chasing they didn't even knew what. I feel so sorry when I ask how are you and the reply is "busy".
