A day is a series of moments you will mostly forget. Some of these moments will make you feel good. Some will make you feel bad. Most of them won't register anything. Yet, we will group all of these moments together and label them bad for pity or as an excuse for everything that goes wrong.
Worse, we will label a day filled with a high number of good moments as a good day. This is an excuse to look to the future with the fear of our luck running out. It also takes credit away from your own accomplishments
Take each moment as its own and at the end of the day don't average them out to decide how your day went. Your day simply went as will your next.
