As a person, everything you do improves over time through practice.
For example, I pay the clarinet. When I first started, I could barely make notes come out, and through years of hard practice, I get plenty of solos, can play All major scales, a lot better than I was.
And I can still improve.
Three years from now, if I continue on with it, I'll be even better, the music I find challenging now will be a piece of cake then.
But I still will be able to Improve.
Another thing I enjoy doing is art.
Here's a piece I did in 2017;
I'd like to think that it's pretty good, right?But it definitely could use some Improvements.
Now, here's a piece I drew today, in early 2019;
This needs no improvement.
