How to have a good day everyday?

I know that when I DON'T have a good day it is because I have made a Judgement that the day, and things that happen during the day are not to my satisfaction.

I have the option, the choice, to not do this.

I am not God and I don't believe I can really know the truth.

I know what I 'think' is the truth, but, Humility allows me to realize I can always be factually wrong.

Now, I still have to make decisions to get through life, but, this requires me to Evaluate things it does not require me to Judge things.

The difference is that when I Judge things I can reject them based on how I feel not on what is true. When I Evaluate things, I consider facts that I may not agree with.
