Self-disciplined begins with the mastery of your thoughts. If you don't control what you think, you can't control what you do. Simply, self-discipline enables you to think first and act afterward.
Such as are thy habitual thoughts, such also will be the character of thy soul-for the soul is dyed by the thoughts. Dye it then, with a continuous series of such thoughts as these-that where a man can live, there if he will, he can also live well.
Take time to deliberate; but when the time for action arrives, stop thinking and go in.
Stephen R. Covey
The environment you fashion out of your thoughts, your beliefs, your ideals, your philosophy is the only climate you will ever live in. The key is in not spending time, but in investing it.
The game of life is the game of boomerangs. Our thoughts, deeds and words return to us sooner or later, with astounding accuracy.
The inner thought coming from the heart represents the real motives and desires. These are the cause of action.
Joseph Edward Murphy
The law of attraction attracts to you everything you need, according to the nature of your thought life. Your environment and financial condition are the perfect reflection of your habitual thinking. Thought rules the world.
Norman Vincent Peale
The person who sends out positive thoughts activates the world around him positively and draws back to himself positive results.
