At some point I decided I could not do this anymore, and quit my job, following that I have spent then about a year playing music and basically doing nothing. it took me a year to recharge my batteries, and it wasn't easy, I had to struggle with depression. But all in all, I learned allot, I pace myself much better now, and spend much more time on things I value, mainly my friends and loved ones.
sometimes you need a break to gain perspective, and rediscover the things you love to do.
However, I was also much less interested in "computers" than I had been all my life. For a few years, I left work at the office and found other hobbies to take up my spare time. That interest has since come back in a very strong way, but I think the mental break I took over that time has helped me out by making me a more well-rounded person.
I'm planning to take another sabbatical towards the end of the year. This time, it's being planned and will not be an emergency.
