Yeah for what it is worth I did a degree in Biology as it was something that interested me and afterwords worked in that field for a couple of years for not much coin.
I now work in manufacturing in a field which doesn't really interest me all that much, but it allows me to do all the things I love in my spare time.
I find I'm much happier now than I was before in life.
If you look at daily life it can be basically broken up into 3 parts. Work, Sleep and Peronsal Time. We all need to sleep so there is not much that can be done about that time - but the other 2 you can choose to a degree how you spend it. I don't hate my job by any stretch and I work my best at it - but I'd happily do another that provides me with the same personal time lifestyle even if I didn't like it much either.
