Worst case you’ve learned something new or had fun.
I am yet to regret a single instance when I regretted sharing unfinished, scrappy work:

One approach I really liked was the 2/2/2 rule:
2 hours for a poc → does this even make sense?
2 days for a prototype to share with friends
2 weeks to build something useful (paid if your goal is to charge for it)
You can leave the process at any stage. Each stage teaches you something new.
