After 15 years, my recipe for getting better. Remain curious and constantly confused. Do not use 'to be' verbs when describing interests or skills. Oh and most important. To do it all for fun not because you want to 'improve' yourself. The rest follows.
I'm curious, would you elaborate on your reasons to avoid "to be" verbs?
For example, you can't say: Lua is better than Python[2]
Instead you say: I prefer Lua to Python
Or perhaps you say: More projects that I rate highly use Lua over Python.
Or maybe: Lua scores more highly on common performance benchmarks than Python

[2] Just an example; I'm not actually saying Lua is better than Python
