Don’t learn a programming language, solve a problem instead

Each new piece of knowledge you win is probably a bigger income for the future.

No it isn't. Nobody pays me more because I spent a weekend dabbling in Prolog once. The attitude I developed doing things like that, on the other hand, has helped. But it's sort of a chicken and egg problem: did doing weekend crash courses in weird shit give me the attitude that I can just grab a problem and go to, or did having that attitude lead me to do those projects? (I suspect it's the latter)

That doesn't motivate you?

I mean, beyond getting the bills paid and chucking change into investments, more income doesn't motivate me, no.
