My skill set and abilities increased the most rapidly in the job before the 60% raise. It then increased further in that job, but because it was a bigger, more established company, it took longer to get exposed to different things, and because my skill set was already larger, fewer of those things were as brand new.

Stress level was about the same as a result: on one hand, I had more to lose - my other jobs hadn't paid nearly as well. On the other hand, I found I had a broad enough base of skills to be useful immediately plus was becoming more confident in my ability to learn things.
