Thinking things has been done through the ages; knowing things remains to be done.

The key to every man is his thought. Sturdy and defying though he look, he has a helm which he obeys, which is the idea after which all his facts are classified. He can only be reformed by showing him a new idea which commands his own.

Think twice before you speak, then say it to yourself first.

Think all you speak, but speak not all you think.

What your heart thinks is great, is great. The soul's emphasis is always right.

Why should we think upon things that are lovely? Because thinking determines life. It is a common habit to blame life upon the environment. Environment modifies life but does not govern life. The soul is stronger than its surroundings.

When we talk in company we lose our unique tone of voice, and this leads us to make statements which is no way correspond to our real thoughts.

Each thought that is welcomed and recorded is a nest egg by the side of which more will be laid.

Thoughts is subversive and revolutionary, destructive and terrible; thought is merciless to privilege, established institutions, and comfortable habit.

Make not your thoughts you prisons.
