Jianfa Tsai’s Input
“Visualise your lifespan as a birthday cake cut into quarters, with each quarter representing 20 years of life. Some people finish the cake, others don’t.”
Explanation Like I’m 5
Imagine your whole life is like a big, delicious birthday cake that is sliced into four equal pieces, where each piece counts for 20 years of growing, playing, and learning. As we get older, we eat our way through the cake piece by piece, and while some lucky people get to finish every single bite up to 80 years or more, others only get to enjoy a few slices before the party ends.
Most Important Point
Time is a finite resource, structured in distinct 20-year chapters, which underscores the importance of fully appreciating and utilizing the specific life stage we are currently experiencing.
