That's the exact path that I want to take. It's something that has led me to many an argument, as I know a lot of people that say "a job is a job, you should be happy to have one". No. I shouldn't be if it's not a job I'm not happy working. Less pay for a more interesting and/or fulfilling job is an easy trade off to make, or an entirely different job. There's so many possibilities that if something isn't working, it's probably work the risk to try something else (assuming family, significant others, money, etc don't pose an issue). Very hard work is typically very fulfilling work.
I'm in the same boat. I've been a web developer for the past 5 years and was getting pretty fed up. I recently changed jobs because I assumed it was my employer that was causing me to become fed up but to be honest I think it's the job itself. I've very lucky (or am I?) that I live with my parents (being of Indian origin that's the norm) and I'm pretty frugal so have saved up a lot of money. I'm really thinking of going back to college to do something like barbering.
