Seth Godin’s recent entry reads like advice for working professionals—do work you can believe in. Not someday when you get the perfect opportunity, not reserved for that day when you have the title or salary or potential reward you’re hoping for. Do it today. Repeat it often enough you’ll get good at doing even more difficult work. And eventually, you’ll have a string of work that you—and likely plenty of other people—can believe in.

But what a great message for high school students, too.

Every day, ask yourself if you did work you can believe in. Don’t base it on the grade, test score, award, honor, or other outside measure. Yes, those have their importance, too. But this is you measuring yourself against yourself.

The effort you expended studying for your French test. The way you left it all on the field for lacrosse tryouts. The comraderie the club enjoyed during the fundraiser you organized. The energy you put into your volunteer work, the contributions you make to class discussions, the conversations you have with customers at your part-time job. Do it in a way that you’re proud to call it your work.

Don’t worry about getting credit. Don’t obsess about the college admissions worthiness. Just get in the habit of consistently doing work that you can believe in.

It’s hard to imagine that habit taking you anywhere but good places.
