The wise and the thoughtful have never placed limitations or restrictions on themselves in their particular field of endeavor.
Limitations are always easy to establish---in fact, too easy. Every time we reflect on our inability to do or accomplish something, we are setting up an increased barrier to the doing or accomplishing. Every time we have an alibi for undesirable results we may have achieved, we firmly establish the alibi as the limiting factor for our future activity. Every way we turn, we find that for the most part, we are spending our time setting up and maintaining limitations rather than removing them and moving ahead free and unrestricted.
We have been using the limitless potential of the power of thought to impose limitations in every aspect of our lives. Once we become aware of this, the power of thought can be used more constructively.
