I am retired now, but things like photography and piano always rewarded my efforts. So did raising a wonderful daughter. She got an honors psych degree and always recommends a therapist. I tell her that I'm too old to fix!
Your programming efforts are the means, but also an end. You'll grow from them, and even if your app is not a "killer" app, your work will find a use. I had a wild variety of jobs and always had to learn new things for the next one. In the process, I found that "good homework always pays off" eventually.
I hope that your efforts bring forth your desired result, but be prepared to be surprised if you succeed in unexpected ways.
Health is wealth, too.
Bought protein shakes. But ordered some Popeyes bad choice but it’s ok
You've started to take action, and that is great.
