You may not think you are capable of anything that could carry the depth of meaning described here as necessary for your life’s purpose. Sometimes, what makes a person exceptional is not their capacity to do what no one else can, but their willingness to do what no one else will.
If you ever find yourself contending against self-doubt, just open your eyes and take a look around. Note how difficult it is to find people willing to be consistently good, consistently reliable, or consistently helpful. There are many willing to do what is easy, but far fewer willing to do what is difficult.
Though differences exist in capacity, there are far more critical things left undone due to unwillingness than there are those left undone due to lack of capacity. The modern world sorely needs engaged fathers and mothers, reliable friends, and helpful mentors—none of which requires any special talent, but all of which require uncommon willingness. Competent and trustworthy workers are hard to find in any field. And the list goes on and on.
You can impart a tremendous difference in this world without any special capability at all just by being the only person willing to do what everyone could and should. All you need is an uncommon heart, and that’s fully your choice—no special ingredients required.
