It's pretty easy for any of us to focus on the knowledge and skills that we don't have rather than fully utilizing the knowledge and skills that we do have. Each of us is endowed with a unique, special set of gifts that we can use to fully realize our destiny.

Keep in mind that just because you do not possess a certain level of skill or knowledge in a particular area does not mean that you cannot possess that level of skill and knowledge. Far too often we have our judgment clouded by what we believe we cannot do. We must always understand that no matter what that we can achieve something if we just try. Let's not focus on our weaknesses so much that they keep us from trying. We all know that not trying is the same as not living.

So go ahead and take some action. The wonderful thing about action is that you will always be rewarded for your efforts. By that I don't mean that you'll necessarily hit the target you aim for each and every time. What I do mean is that each time you miss the target should serve as a valuable learning experience. This experience will allow you to tweak your aim and hit more targets more often in the future.
“Do not let what you cannot do interfere with what you can do.” – John Wooden
