Obstacles can't stop you. Problems can't stop you. Most of all, other people can't stop you. Only you can stop you.
Let me tell you the secret that has led me to my goals: my strength lies solely in my tenacity.
Motivation will almost always beat mere talent.
If you get tired, learn to rest, not to quit.
Continuous effort - not strength or intelligence - is the key to unlocking our potential.
Perseverance is the hard work you do after you get tired of doing the hard work you already did.
A little more persistence, a little more effort and what seemed hopeless failure may turn to glorious success.
Talent is nothing without persistence.
In an age of distraction, attention is our greatest asset.
Simplicity and sincerity generally go hand in hand, as both proceed from a love of truth.
