Yes! There were days when, in doing something that I felt was an achievement or small victory on my part it gave me a sunnier disposition. I felt good that whole rest of the day. For instance if I had a routine down, walking in the morning and cleaning the house, but if I skipped a day I felt awful. Then my spirits were so low I'd just quit that routine because I felt as if I had already bombed it. But I don't do that anymore. I try to make sure I find one positive thing to do that day, no matter how small and it gives me a nice boost.
It also helps to keep a good attitude
If you go to bed thinking the next day will be lousy for you, more than likely you'll wake up with the same attitude.
