A simple CRUD app is magic to the average user, if it does something they haven’t seen done in software before - and that could be as simple as some calcs in a custom domain.
The first customer who tells you “this is great”, if it’s anything like my experience, changes everything.
It also helped that some of my early forays were to clean up code by a guy ten years my senior which was rammed with bugs - fixing those one by one was satisfying and helped me earn trust with my team and in myself.
