Learn from Mistakes

So, I learn from my mistakes. It's a very painful way to learn, but without pain, the old saying is, there's no gain. I found that to be true in my life. You miss a lot of opportunities by making mistakes, but that's part of it: knowing that you're not shut out forever, and that there's a goal you still can reach. Johnny Cash
