I had about 15 jobs over 40 years, not including 9 years at the two companies I started. But some were short term contracts, and several (in a row, sadly) ended in my employer going out of business, mass layoffs, etc. I always found doing something new was revitalizing. Also found that sometimes something new was awful. Being comfortable changing what technologies you are expected to use helps, taking advantage of new tech being new, and not many people knowing it, is good too. At my last job before retiring I stayed for 5.5 years, and could still be working there today, except it was enough of a career.
