I would maintain that thanks are the highest form of thought; and that gratitude is happiness doubled by wonder.

Concentrate all your thoughts on the task at hand. The sun’s rays do not burn until brought to a focus.

If you don’t like something change it; if you can’t change it, change the way you think about it.

Happiness is when what you think, what you say, and what you do are in harmony.

Your worst enemy cannot harm you as much as your own unguarded thoughts.

We cannot solve our problems with the same thinking we used when we created them.

We need not think alike to love alike.

We must never forget that it is through our actions, words, and thoughts that we have a choice.

Think like a man of action; act like a man of thought.

You get peace of mind not by thinking about it or imagining it, but by quietening and relaxing the restless mind.

Those who are free of resentful thoughts surely find peace.

The thought manifests as the word. The word manifests as the deed. The deed develops into habit. And the habit hardens into character.

All that we are is the result of what we have thought. The mind is everything. What we think we become.

Since you alone are responsible for your thoughts, only you can change them.
