Agree with focusing on doing it because you enjoy it, something gets lost when we try and impress others; I'm sure we can all remember being a child and doing things purely because we enjoyed it. However, I disagree with the personal style part of things, or trying to make things look good. These things don't have to be about impressing an audience. It can be just as much about enjoying the process.
The way I read “personal style” was, don’t make it your whole personality. And making things look good is in the eye of the beholder. If you like design and want to make pretty things, do that and don’t worry about the criticism. For me, pretty is my code, I couldn’t care less about the UX because I’m the only user.
One of those is performative and creates pressure and expectation, often at the expense of personal enjoyment and rest. The other is just finding the bit that's interesting to you.
