Professional athletes play in all sorts of conditions. They play when they’re injured. They play when they’re sick with the flu. They play through heartbreak. 

It’s not ideal, but setbacks happen—and athletes keep playing.

This philosophy and practice can apply to all sorts of other fields. (For example, advertisers keep advertising.)

When you play through this, and endure the difficulty, you develop something very valuable that can’t be bought.

Some people call it character, other people call it confidence, and still others will call it by another name. Whatever it is, it’s very special, and it’s extremely valuable.
