Planning your next move is important at any age. No matter how he sliced it, fun ensued.

Even when vis à vis certain joy, stress will accompany thoughts of missed opportunities. There is little wonder why moments followed by impulsive leaps are often joyous: they leave little room for stress and allow the mind to focus on things to come.
This is by no means a perceived rule to follow. Dynamic situations often have a windowed time in which control can be taken. Absent control, what comes will come. This too might lead to joy, but not the kind of which one could take credit for – if that is a factor worth your consideration.
Compounded throughout time, decision gates toggled by action or inaction will will have dictated the now.
Enjoy the now!
