Don't Give Away Your Power

This came in my email today - and I thought it was an excellent thought:
"Do you realize how much energy it takes to be bitter or hold a grudge? We only have a certain amount of energy for each day. If we use it for the wrong purposes, we’re not going to have the energy we need for the right purposes. We’re not going to make the best decisions. We’re not going to be as creative. We’re not only doing ourselves a disservice, but we’re doing our family and our friends a disservice.
Remember, you can’t control what people do or say. You can only control yourself. If you’re allowing others to upset you, then you are giving away your power. ... The reason many people have no joy or enthusiasm is because they go to bed every night with anger and unforgiveness. When you go to bed like that, with a cluttered mind, you wake up with the same negative emotions. Choose to let those things go so you can live in the peace, joy, and power the Lord has for you."
