If you want to try getting back to the root-roots, you could try following Ben Eater's youtube series and build an 8-bit breadboard computer, and write some software for that; I find hardware fascinating.

Alternatively, find a cause/issue you feel strongly about and see if you can apply your skillset to make real change, where you can feel good about what & why you are coding. Or another way to put it, let programming be secondary to a more important goal; your desire to accomplish that goal will drive your need to improve as a programmer.
