A new realization ever since becoming a father, and having a newborn child:
Making long-term, or even weekly plans is not good. Best to take it moment by moment, day by day.
Things we cannot predict
For example, how can I plan the next day, when I don’t know how well (or poorly) I’m going to sleep that night? What if the baby keeps me up all night?
Also with basic lifestyle things — I don’t know how my child will act and behave during the day, which means:
Harness the maximum out of every moment, and try not even to plan a day ahead!
The maximum wisdom:
Approach every day as a new and different day, and cherish every moment.
