Early fifties here. > Your use of the word "burn" concerns me. I'd prefer the word "invest". I agree, but... sometimes it really is "burn". I don't keep up with front-end tech these days. If/when I need to work with it I'll learn it, and not before. If I spent time getting up to a real working knowledge now, there's every chance that in, say, 4 years when I needed to work in that space that I'd have to start learning from scratch again rather than brush up. I do spend time learning new (to me) things, but I'm very selective. I devote most of my time to learning things that will give me alternate ways of doing things, rather than learning every nut and bolt of the latest framework.
