There is a wonderful saying in the martial art of Jiu-Jitsu:
There is no losing in Jiu-Jitsu. You win or you learn.
This quote comes from one of the pioneers of Brazillian Jiu-Jitsu, Carlos Gracie Sr.
What I love about it is how succinctly it demonstrates the value in learning from trying new things.
When it comes to innovation and developing creativity, it is a necessity to try things which could not work out.
Others are often afraid of pushing through this step, since they equate not succeeding as failure.
And they think failure needs to be avoided at all costs, because this is what they were taught.
But if instead, we see trying something and not succeeding instead as an experiment or challenge from which we learn, then we can switch that thinking into something positive. Like how a scientist sees a failed experiment as a positive step to improving the next experiment, on the way to the final correct answer.
You win or you learn.
