Except "taste before skill" is a well known issue and source of frustration for starting artists: They can already see what's good and they know what they want to do, but they don't yet have skill in measure with their taste and get locked in a feeling of inadequacy. They resolve that if they stick with it. So, taste looong before skill.

So...

> If you don't tinker, you don't have taste

> Acquiring good taste comes through using various things, discarding the ones you don’t like and keeping the ones you do. if you never try various things, you will not acquire good taste.

No. That's not how it works.
