The motto of a successful person and a successful entrepreneur is "continual improvement".
Everyone makes mistakes, nobody is perfect. It is not possible to attain perfection, but if we pursue perfection, we may catch excellence.
When we make a mistake, the best course of action is to recognize the mistake, admit the mistake, and take corrective action including learning from the mistake to hopefully never make it again. This is continual improvement.
Everyday we should take a small step toward our goal, toward perfection. And even though we know before hand that we will never reach perfection, those small steps we take every day will give massive results over time.
Do not get disheartened when you make mistakes. Learn from them. Commit to the motto of "continual improvement" and you will reach success.
If you can try to be 1% better than you were yesterday, before long you will be achieving things you never thought possible! Nothing can stop a person who is committed and who doesn't give up and who applies this philosophy of continual improvement. Your life will be an amazing masterpiece! Your life will be an inspiration for all those who thought they greatness was not meant for them! Your story will be told for generations! Your name will be in the hall of fame!
But you wont get there overnight, or even in one year.. You have to commit long-term to progressing each day, to taking each obstacle as a learning experience, and to continually improve in good times and in bad. You can do it!
