Henry David Thoreau
A man is rich in proportion to the number of things which he can afford to let alone.
Paramhansa Yogananda
Be careful what you choose to do consciously, for unless your will is very strong, that is what you may have to do repeatedly and compulsively through the habit-influencing power of the subconscious mind.
Epictetus
When something happens, the only thing in your power is your attitude toward it. It is not the things that disturb us, but our interpretation of their significance. Things and people are not what we wish them to be nor are they what they seem to be. They are what they are.
