"Watch your thoughts, for they become words.
Watch your words, for they become actions.
Watch your actions, for they become habits.
Watch your habits, for they become character.
Watch your character, for it becomes your destiny"

Our mind is extraordinarily powerful. Our thoughts control and decide almost everything that happens to us. Image our thought can control our heartbeat, affect our general health, our sleep or keep us wide awake all night.
Our thoughts can set us humming with joy or pull us down with sadness. They can make us alert and aware or distract us. They can pep you up with confidence, powerful or otherwise insecure and helpless. See how powerful our thoughts are.

And the best part is our thoughts are completely under our control.

"We are shaped by our thoughts; we become what we think. When the mind is pure, joy follows like a shadow that never leaves." -Buddha
