Good Heart Positive Attitude

I am not a carefree person. This bothers me. I think too much. I discover things I wish I didn't. In all of this thinking lately, and quite possibly sleep deprivation I have decided to hell with thinking, excuse my language. Analyzing things can make them confusing. Wondering why people can be so self absorbed, needy, taking, oblivious, wonderful or not wonderful, confident or not is a waste of time. We can not control how other people behave, what they do or what they think. We can't make them treat us better, pay more attention to us, pick up their phones, listen to our problems, we can't control what they say behind our backs.
We can only control ourselves. We can only know what we know no matter how influential others may be.
By having a good heart and a positive attitude I believe things will work together for our good. Being a religious person has a lot to do with the good heart part, but even if you aren't religious I believe in karma, I believe things will work together for your good if you have a good heart. And if nothing else at least you will have a good conscience and an easy stomache. If you have a positive attitude you can avoid a lot of the negativity thrown at you or plain shoved in your face. Maybe you can more willfully take care of you family or serve your whomevers.
All I am saying is life is hard. I am not a carefree person. I work on being positive. I work on being happy. Selfishness is not something I take easily (although some would suggest otherwise). I like to give, I like to listen. I do not like it unrecipricated. Who does? I do believe that we should be good, selfless, honest, giving people whether it's recipricated or not. To everyone? Of course not. Don't let yourself be taken advantage of. I am going to work harder at having a good heart and a positive attitude. For the rest of my life.
