Here are some quotes that I found about pushing yourself:

- “It’s important to push yourself further than you think you can go each and every day―as that is what separates the good from the great.” – Kerri Strug
- “Running alone is the toughest. You get to the point where you have to keep pushing yourself.” – Walter Payton
- “It’s all about taking risks. Push yourself to do as much exploration as possible.”
- “Push yourself because no one else is going to do it for you.”
- “Constantly push yourself higher and harder until you reach your goals.”
- “Push yourself again and again. Don’t give an inch until the final buzzer sounds.” – Larry Bird
- “Get out of your own way.”
- “Reach for it. Push yourself as far as you can.” – Christa McAuliffe
