What is failure? Is it not being able to close a deal or is it something we just thought we would succeed at but didn't? Failure is a funny thing, in most cases people view it as a step back or something they will never get over. I do not believe in failure, I believe that failure is an opportunity waiting for a solution.
We can take failure and turn it into something positive, as long as we view it that way. It is hard to overcome failure or even a mistake. Failures and mistakes are only such if we do not learn from them. There is always something to gain when things don't go the way we planned, they are learning experiences. Albert Einstein said "the world as we have created it is a process of our thinking, it can not be changed without changing our thinking". This is a vital thought process to transforming failure into a positive situation. We need to change our thinking so we can continue to learn from our experiences.
The next time you feel like you have taken a step back or made a mistake, learn from it. Know that everything has it's purpose. As long as we can continue to strive towards our goals with a positive manner, anything is possible. If you want it bad enough, you will figure out how to make it happen. Remember, failure is only something that happens when you give up.
