I think it depends entirely on your personality, assuming money is not the issue. I got out very young due to an injury, but haven't really looked back.
I'm so busy day to day that I marvel at how working people survive, but that's because I have a bunch of oldish cars, a 27 acre property that requires attention, a couple horses and serious cycling and gardening addictions. Don't travel, too busy.
If you don't find yourself needing time for what you would do if you didn't work, then maybe keep working. If you have one passion, not enough.
But the simple fact is, the one thing you can never buy, no matter how hard you work, is time. So if you can use it in a way that is more interesting to you than work, stop.
