> become a specialist Any suggestions for a specialization? I've seen a lot of specialities become worthless or at least marginalized. I'd like some examples that stand the test of time. (For tech that's probably 10± years). Ive seen plenty of niches were a few folks were able to cling like barnacles in Finance, Telco, etc but TBH their lives didn't seem that appealing. Lots of time on the road, etc.
