“Still more apparent does the working of this principle become when for the word ‘idea’ I substitute the word ‘purpose.’ Purpose at once suggests the notion that the person whom it actuates is in motion toward an end; and a person moving toward an end, like a rifle-ball toward a target, is less easily managed and directed than when he is standing still. Indeed, the more rapid its motion the more difficult it is to change its direction, and the less effect influences that happen to lie along its route will have upon it. Now, what momentum is in the rifle-ball purpose is in a man: it tends to hold him steadily to the track he is on; and the more vigorous the rush of intention with which he is following that track, the more it will take to retard him or derail him. Hence the more intense and engrossing a man’s purpose— if it is a purpose of good —the safer he is, and if he has no purpose of the kind he is not safe at all. Without it he is spoil for any and every diverting influence that may happen to light upon him, and of such diverting influences the air is all the time full.” – Charles H. Parkhurst
When most people articulate their purpose, they see it as relating to some pattern of outer achievement. To my mind, such purposes are valuable and contribute positively to the betterment of humanity, but true purpose relates to something deeper.
Your true purpose is less a matter of construction and more a matter of revelation. You do not necessarily reveal your true purpose by building a form to accommodate your vision, in fact, the forms you end up using in the revelation of your vision are largely incidental. The revelation of true purpose requires a fidelity to a central pattern of spirit, such as blessing, healing, forgiving, inspiring, amusing and so on.
Which spirit would you say is your central responsibility to uphold and represent, come what may? Discover that and you will never be swayed, fooled or confused again by that which seeks to distract you and keep you from being meaningful.
