One fun fact: if you plan to live to 120, you do not have to be middle-aged until you are 60. Even so, most of us have entered or are getting close to the second half of our lives.
With more time behind us than in front of us, prioritization is becoming more important, and what is important changes through the cycles of our lives.
In my twenties, I took a year off from studies and work to stay home and look after my two sons, an infant, and a toddler.
This phase in my life was gratifying because I was able to let go of some of the everyday tasks that had taken up all of my time.
Prioritization at work also changes over time. In younger adulthood, such priorities are primary. There are careers, reputations, and an income base to establish.
