Dots

He dropped out of college and, with nothing better to do, wandered into a calligraphy class. Serifs. Letter spacing. Why some typefaces look beautiful and others do not. It had no practical use at all. He took it because it was lovely.

Ten years later he put all of it into the first Macintosh, which is why the screen you are reading this on has fonts that do not hurt to look at.

He could not have planned it. Nobody can. The year that went nowhere, the degree you never used, the thing you learned on a whim and felt silly about. Dots. You will not see the line until later. Your only job now is to collect them honestly.
