I ran across this article with a developer thinking that not coding or learning at home was a good to learn. Do you think it is important to code/learn in your spare time? Does programming only at work make someone a better programmer. https://jvns.ca/blog/2017/08/06/learning-at-work/
Knowing more ways of tackling more problems makes you a better programmer. The more difference there is between what you do at home and what you do at work, the more you will learn. If at work you write C/C++/Java, learn Haskell at home. If you do GUIs at work, do low level coding at home. (And vice versa, of course.) Me, I play with SMT solvers at work and I build my own keyboards at home.
