What is this font good for?
Ooh! Isn’t this one pretty? I wonder what I can use it for.
It seems to me that the right question to ask is this: How can I solve my design problem? In answering that question, I’m sure I’ll find an appropriate font, but font selection is the output of the design analysis, not the input.
Fonts are like buttons in your grandmother’s button box. The reason she kept a box full of buttons was that it increased her chances of finding the button she needed when she needed a button. She didn’t stare at the box wondering what she could use them for. Ooh! Isn’t this one pretty? I wonder what I can use it for. No. If a garment turned up in the laundry missing a button, she could then go to the button box and look for a suitable replacement. She began with the design problem and went to the button box to solve it, not the other way around.
