Sometimes the experience we may might think is our worst situation might be the turning of the propeller that enables us to fly. I regret nothing. Sure, knowing what I know now, I might have changed a few things. But, sometimes going through these tough times, builds someone up to the person they are supposed to become. Not having these experiences as a building block would have made tough experiences much more difficult, if not impossible to overcome.
"No one can make you feel inferior without your consent." ~Eleanor Roosevelt. I have learned I am who I am. I am on a path. This path is not free of debris. But realizing you are able to get past any situation creates a champion mentality. It's not easy. But it does build you for the other challenges that life has to offer. The building blocks of life that you choose how to accept.
