Are you a Polymath/ multi-skilled? And how did you do it?

Its not being a jack-of-all-trades, but at the common sense you have a lot of skills that can be traded for niche and can be useful if applied as profession despite being in your career path or business.

What are you working at right now? (Which can be your jack of all trade skill)

How did you come up to be multi-skilled? (For others to get inspiration, etc.)
