What you think of yourself is much more important than what other people think of you.

The greatest weapon against stress is our ability to choose one thought over another.

The primary cause of unhappiness is never the situation but thought about it. Be aware of the thoughts you are thinking.

To find yourself, think for yourself.

Thinking will not overcome fear, but action will.

Clear thinking requires courage rather than intelligence.

Get out of your head and get into your heart. Think less, feel more.

Nurture your mind with great thoughts; to believe in the heroic makes heroes.

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.
