I find the best way to build self-confidence is to keep trying and do better. What I mean by this is that the first time you do something, you’ve done your best. But doing it again and trying something new is doing better than last time. That gives self-confidence, because you see that you’ve done better.

Don’t compare your work to others’, because you’re probably seeing their work after several cycles of getting better and comparing it to your first or second go-around. That will erode self-confidence every time. Measure your own improvement and keep practicing. Keep learning. Keep trying new things.
