I think it is safe to say we all want a good day. You wake up in the morning wanting the day to be good.
But what is a good day to you? In other words, what would constitute a good day? How would you measure it? If your aim is for a good day, then perhaps you need goal posts to mark what would be considered a good day. A goal you aim for, so to speak.
Otherwise, how do you know what to aim for? How do you judge the day when it ends? Would a day with one bad event and a series of good events be good or bad?
To create a good day, you need to know what a good day looks and feels like.
Do you know it even when you see it?
