I could never be as hardworking as my father. I had grown up hearing stories about how he started helping with the family's income when he was a young boy. Somehow, he always managed to ace in his studies and sports as well. Even though I thought I was doing pretty well compared to my peers, to my father, I was not making the best use of time.

"Waste of time in your prime is a crime, my boy!" my father would say whenever I was floating aimlessly in the swimming pool.
At any moment I felt lazy, my father's words would echo in my ears like the ringtone of an alarm.
