Curious, my boss's dad has a phrase "prohibited the error", I think I hate that phrase... and I keep saying, nobody make a mistake because we want. NOBODY. And replay to that, if we were perfect we´ll be in heaven. The reason we are here, in this world is to learn...
I have always thought that, it is right, we are spirituals being in a human life, so , our work here is to learn . you can learn without making mistakes it is true, but the learning derived from the mistake made is stronger. So, all we have to do is review our decisions and actions and avoid to make it again. It is not that you are going to make something wrong to " learn" , it doesn´t work that way either...
