I've just turned 40 this year and the thought of working in my current profession for the next 25 / 30 years is very disheartening. The issue is that I like the people in my office, I get to travel to some interesting places and I get paid a decent salary which makes it hard to make a decision to leave (I've also been there for 19 years so it's all I've ever known).
I sometimes wish I could retrain completely to do something else but I don't have a passion for anything in particular and I know I'd have to take a big pay cut.
Has anyone been in this position (I'm sure there are plenty), what careers have you gone into and how did you make the decision?
