Learning to laugh (or at least to have a mental chuckle) at yourself can make mistakes more enjoyable. When I was first learning to use clipless pedals, my wife loved to laugh at my tales of what I called my "0 mph crashes". It was great fun describing what it feels like to be on a bike that stops moving forward while your feet are trapped on the pedals and the bike inexorably, and almost in slow motion it seems, flops on its side. It's all fun as long as the injuries are mostly to your pride and your bike can put up with the abuse.
