20, 30, 40, 50

in 20, you start listen and learn from ppl

(as you still fresh in life, better to follow what been told)

in 30, you start talking and sharing to ppl

(as you think you had all the infor in life, why not share)

in 40, you start order and commanding to ppl

(as you think you know all about life, and ppl should follow what you say)

in 50, you start organise ppl life

(that is what you good at now, and making ppl hate u)
