Experience comprises knowledge of or skill in some thing gained through involvement in that thing. Experience comes from making decisions, whether they have good or bad outcomes. If these decisions have bad outcomes, it means that we are making something new and this helps us gain experience. And the experience we gain helps us make better judgments in the future. So, the experience that we gain by making bad decisions will helps us in the future.
You can’t succeed if you don’t try. If one tries, one may fail. If one never tries, one never fails but never gains either.
