There's no true right answer here, it depends on what you want to achieve
>learning
you can sit on the same project for weeks and months and keep improving it while learning various skills that will translate to your later projects, like:
>make donus
>look at it
>hate it
>make a list of singular things you can improve
>glazing texture
>lightning
>color
>more interesting shape
>more realistic background
start researching the topics one at at time and improving them, render the same thing with improved thing, you'll likely learn something you can use for later projects

alternatively just start another project and try to apply what you'd learned, when you get stuck just google / research a specific thing you're stuck on, try to learn / improve that as you work on this project

Honestly there's no right answer, if you're just doing this for fun keep working on a project as long as it's fun and you want a better result, if you just cba or feel like you need a change, do something else.
The main thing is to understand concepts in a way you can apply to future projects, not just blindly following tutorials. However whether you achieve that through sweating on a single donut for 300 hours or by making 300 1-hour donuts does not truly matter.
