Reality is what's in your head. The brain is 70-80% water and the rest is made up of fat and protein. It has never seen the world. What goes on inside is up to you. When I have feelings of jealousy, I stop myself and think of three things I'm grateful for. When I make a mess of things, I think of three things I did well.

I'm not perfect at it, but I remind myself I can get better.
