Every failure teaches us something, so failure is just a step on the way to success.
Failure can be delayed, but it can never be avoided. So fail, learn, and continue.
In a year or so, you will look back at your 'fails' and think that they aren't so bad...
Just so you know, I actually took all the quilting out of one quilt that I quilted. It was really horrible - not kidding - unbelievably bad, the quilt was useless when it was done. But I learned so much from quilting it, that I don't consider that a failure. A few months later, I quilted it again and it came out very nicely.
Did I mention that I am an optimist?
