Instead of criticising yourself for so called "failures" try to see it all as a process of improvement, of adjusting your course and learning from the results that you get in your life.

In his book The Success Principles, Jack Canfield suggests we change the way we think of failure, so that we see it all as "feedback". If things don't go to plan, see it all as useful information that you can use to help you to get better, rather than taking it to mean that you're not good enough.

JK Rowling had her first Harry Potter book rejected by 12 publishing houses before it was accepted, Thomas Edison purportedly attempted the light bulb with 1000 different materials before finding the right one, while Colonel Sanders was said to have been given 1009 "no's" before he was given a "yes" to buying his famous chicken recipe that began Kentucky Fried Chicken.

If these people had taken things personally after a few failures, they would never had had the success that they achieved.
