One thing I have learned by working for myself over the years is that mistakes will be made. You pick yourself up, you move on, you fix it and do it better. But once you fix your mistakes and things run smoothly, do you stay in that spot? Do you work off the mantra, "If it ain't broke, don't fix it?" Or should you push the envelope and make changes, try new things!
So as an entrepreneur try new things, push your envelope and see what it brings! Don't be afraid to make a mistake. You will learn, you will recover and you will be better for it!
