Leave no stone unturned.

Continuous effort — not strength or intelligence — is the key to unlocking our potential.

The secret of success is conviction and persistence.

You have to be burning with an idea, or a problem, or a wrong that you want to right. If you're not passionate enough from the start, you'll never stick it out.
