You sound like you're very early in your career. It took me about 8 years before I found a job that I really, really found interesting.

Think about it this way: The real interesting jobs don't take chances on recent graduates. There's just too much on-the-job experience needed.

The best advice that I could give to my younger self would be to think a lot more critically about when to change jobs. The time that I left the boring CRUD job was a huge mistake. (I should have kept looking instead of taking the job that I took.)

The second best advice that I could give my younger self would be, when in a boring (but stable) job, is to avoid recruiters and try to network more with people doing interesting things. Recruiters are better when you aren't very picky about the kind of job (or employee) you want.
