Sometimes your best thinking will get you into the most trouble.
You do not know everything and when you assume that you do, you close yourself off to the possibility that you are wrong and you close yourself off to the possibility that others could be right.
This is especially true when, for one reason or another, you are determined to hold onto your own ideas in spite of evidence that they are no longer working.
An close-minded attitude coupled with obstinance is a recipe for disaster.
The only real way to ensure that you are right is to be willing to admit that you may be wrong.
This means acknowledging that others may know more than you, that they may have better ideas than you, and that you may need their help.
With an attitude of humility and a willingness to learn from others, your chances of success go up exponentially.
When your best ideas are not working, look to others for help.
If you are unwilling or unable to do this, whether out of pride, ignorance, or fear, you are ensuring your own demise.
Think for yourself, but also use the resources available to you, especially the people around you who are smarter, more experienced, or more skilled than yourself, and you will find that life is not only much easier, but also much more enjoyable.
You are not alone.
