Nature yields her most profound secrets to those who are determined to uncover them.

 The field of science is perhaps the best illustration of how success always seems to come to those who apply the principle of accurate thinking in a persistent, determined effort. America’s great inventor Thomas A. Edison is said to have failed 10,000 times in his attempt to develop a workable electric light bulb. He learned from each failure and refused to quit until he succeeded. Breakthroughs occur every day because a determined person continues to search for solutions to complex problems long after everyone else has given up and gone home. You may not invent the light bulb or the next supercomputer, but you can find creative solutions to old problems if you apply the proven principles of success consistently and persistently.
