My son, who recently got married, is working full time as a teacher, and is making his way in the world is much smarter than me. He proves it to me over and over.
Recently he told me, that to be good you do not have to think positively or make a huge effort at figuring what to do.
He says, think what you want, but do what a good teacher, or coach, or realtor, or husband would do. That will take care of it.
Many times I worry about what I am thinking about something and that thinking can make me feel like I do not know what I should to do. But that is not important. What is important, is to do what a successful person would do.
I think he is very smart.
