Realistic vs Being Negative

Greetings all,

I have been thinking lately the concept of being realistic and being negative. I think many times people mistake one for the other. Like they may be negative when they think they are being realistic or they are realistic but think they are being negative. How is one supposed to know? What makes something realistic? What is being negative all about?

I think for me, something is realistic if I think I can execute it. But on the other hand, maybe I don't think I can execute something because I am being negative about it?

Who knows really and I think the only way to know is through paying attention to your mind. I thought I had more to say on this topic but at this point, this is all I got!
