Your Thoughts Become Your Reality - An idle mind is the devils playground.
Your thoughts are a catalyst for self-perpetuating cycles.What you think directly influences how you feel and how you behave. So if you think you're a failure, you'll feel like a failure. Then, you'll act like a failure, which reinforces your belief that you must be a failure.
Allow garbage in, and your life will feel like nothing but garbage. You are what you think. If you left your garbage pile up in the house, eventually it would stink the whole place up. Allow negative or dark thoughts into your mind, even different spirits, and your body will entertain that and rot your mind, body, soul, and spirit. Leave it all where it belongs...in the trash. Be careful who and what you mess with.
It's never too late to be what you might have been. In the middle of every difficulty lies an opportunity. Change your mind - change your whole life.
