I'm 14 years past you, but have a job that I've learned to like for what it is. After 10 years of it, I was burned out and realized at the time (and sometimes need to be reminded if I get too deep into "trying to do the right thing" longer than I should be trying to do it when someone doesn't want that - as in a client someone) that the idea that our relatives live fulfilled had less to do with how much better their jobs were (they weren't) or their means were (they weren't) and more to do with how they viewed things. They were happy to have a job that they didn't love every part of because some of their relatives literally lived scratching dirt and almost having to resort to eating it.I'm 30 and want to retire now, although I suspect it has more to do with my unfulfilling deskjob writing software for a pensions company than my age. I just want to build my first workshop and make things.
Doing things that you do well at work and making a point of gratitude for it plus a little mini celebration may be as spicy as it gets. Dealing with the parts that you don't like and not letting problems that aren't yours become yours (like worrying about future projects that aren't today, or promotions to a level that you don't want to be in - an actual problem in the past where a supervisor was gung ho to push me into something I despised - he was so confident that everyone just needed to be convinced why his version of them was better than their own)...just tolerate them, do them and let them pass.
My only one personal tip is don't do a job that you roundly don't like at all, spend foolishly and have nothing to show for it (I never did that, but have seen many bounce around from one thing they had to another in haste because they have a burden laying on them. Suddenly around age 50 they decide they're going to save money and settle down, and it's too late. And then at that age, the jobs don't come quite as quickly and easily. )
