My dear,

The two most important days in your life are the day you were born and the day when you find out why.

The day you plant your feet into this world, and the day you find out why you should use them to walk, and maybe – walk far. These are two of the four milestones of your life, they are the most important of the four because the others can’t happen without them, and every day in between is just about learning and building yourself up to these.

The other two milestones are farther down; the third milestone is the day you accomplish your why, and the fourth when you help someone else find theirs.

Falsely yours,
Samuel Langhorne Clemens
