The Prophet Mohammed said, “There is no better companion on this way than what you do. Your actions will be your best friend, or if you’re cruel and selfish, your actions will be a poisonous snake that lives in your grave.” –Rumi
Thinking is the opposite of acting, so if you are not acting you are thinking and if you are thinking too much and acting too little, you are going to have a massive cognitive dissonance and that dissonance can only mean one thing, your mind will work hard to match your actions with your thinking or your thinking to your actions. Unfortunately, matching your thinking to your actions is the path of least resistance and so mind will lead your thinking to closer to your actions and that is simply a race to the bottom.
I’d say you don’t rise to the level of your thinking, you fall to the level of your actions. You can think all the greatest ideas and ideals in this world but they are not going to transform you, what will transform you and make you a better person is when you act on a few of those dreams, ideas, ideals!
