It's what you put in the universe

I'm riding to work today and thinking, I went to sleep at a decent time but I'm tired, I'm exhausted. I thought maybe my meds for making me feel tired but haven't even taken them in a week. Is something else wrong? So I decided instead of every time someone ask me how you doing, I always say that I'm tired but I'm good. From now on, I'm responding with, I'm good.  I want to start putting positive energy in the universe. I have to be careful of what I
put in the universe.
