Practice stalls on your own?

Ok, so say you are post-solo and approved to perform stalls OR you are
a private pilot.

Is it smart to go out and practice stalls on a normal basis? For
proficiency and for fun?

Or are stalls something you should only being doing for training?

I would like to hear from both pilots and instructors on your thinking
of this topic.

Also what percentage of you out there do practice them on your own?

Thanks
