Maybe you need to focus on what you are building rather than how? Programming is a means to an end and not a means itself. I think this is a trap many of us fall into and you see it play out when people end up trying to learn as many different frameworks or languages in order to be a "better" programmer.

At a senior level the difference in programming ability becomes negligible, its what you do with that ability that matters. Here are somethings that a programmer could specialise in:

- building web apps to handle extremely high loads of traffic

- web apps with a heavy focus on security

- embedded systems / low level programming

- computer graphics

- machine learning (warning: the hype around this may skew things)

- blockchain based technologies (warning: the hype around this may skew things)

All of those fields require specialist knowledge beyond the programming language being used. You should focus on gaining specialist knowledge like that at this point in your career. Otherwise there is really not that much difference between a generalist programmer with 15 years experience and a generalist programmer wit 5 years experience.
