Have you ever walked into an office and seen motivational art on the walls? They typically say things like, “Teamwork,” “Focus,” “Integrity,” and other words along with a generic photograph of a distant tree or sand dunes.

Other times, the motivation comes from successful people who have experienced both the ebbs and flow of life and have persevered through all the adversity to get to the top of the mountain.

People like sports professionals.

We’ve found motivational quotes from 15 successful pros that should give you a little boost if you ever find yourself needing one!

“It isn’t the mountains ahead to climb that wear you out; it’s the pebble in your shoe.”
