“And if any appear never to assume the chair, but always to stand and serve, it is because we do not see the company in a sufficiently long period for the whole rotation of parts to come about. As to what we call the masses, and common men;—there are no common men. All men are at last of a size; and true art is only possible, on the conviction that every talent has its apotheosis somewhere. Fair play, and an open field, and freshest laurels to all who have won them! But heaven reserves an equal scope for every creature. Each is uneasy until he has produced his private ray unto the concave sphere, and beheld his talent also in its last nobility and exaltation.”

— Ralph Waldo Emerson, Representative Men (http://www.gutenberg.org/files/6312/6312-h/6312-h.htm)

It seems to me that no person is in a position to judge whether another has found the thing that they should be shaping their life around. As much as we like to assume they are, humans aren’t rational creatures and activities that appear completely pointless from the outside can be incredibly meaningful to the one doing them.
