But while she was in the midst of her Texas beef trials, facing some of her biggest challenges, Oprah came to realize that, "your deepest struggle will produce your greatest strength."

In O magazine, she quotes Eleanor Roosevelt: "You gain strength, courage and confidence by every experience in which you really stop to look fear in the face."

And then, in her own words: "What I know for sure is there is nostrength without challenge, adversity, resistance, and often pain."

In other words, strength and struggle are different sides of the same coin. They are both essential to your life. If you make the mistake of labeling struggle or doubt or fear as bad, you will avoid them. And then, you will miss out on the opportunity to discover your greatest strength.

Now, extrapolate this perspective to everything else in your life. As it is with feelings, so it is with everything else. For example:

If you look at everyone in your life through the 'either/or' lens — either they are good or they are bad — you will miss out on the opportunity to discover the greatest strength that hides within every human being.

Because the intrinsic truth of every human being is also that their greatest weakness is the source of their greatest strength. Weaknesses and strengths are different sides of the same coin. They go hand in hand.

This is one of the key shifts in perspective that is vital to transforming all your relationships and also, to changing the world. It is imperative that you make this shift and that you make it your way of looking and your way of life.
