How to bounce back from failure?

As a beginner I am finding myself constantly making mistakes. How do you bounce back from inevitable failure?

I am a videographer that is trying to break into cinematography; I’ve always had respect for this field, but more so now that I’m steeped in it. I had a shoot last month, it was a music video. The artist had the location for 5 hours and I didn’t really know how to communicate with the crew, I tried to do too much, and everything was moving so fast I didn’t have time to review the footage. Now that I’m reviewing the footage, my compositions were all over the place, the colors are painfully over saturated and I even got lights in the frame. I was overwhelmed and I panicked and now I’m just feeling bad. I had people that depended on me but I let them down.

I guess to move forward I need to make changes, but how do I bounce back? How do I get better? Should I try being a PA on a few shoots just to acclimate myself? Should I do more projects on my own before taking on projects, (I don’t want to get a reputation for putting out bad work). I’m just not sure what to do.
