To the gentleman who admitted that he was not working hard enough during school days, always playing a fool.

It's the reality of life. Every phase of our lifetime has some responsibilities to perform. If we do not do the right necessary things in each phase, our next phase will be uncertain. This is what we need to ensure that our kids understand, but in reality many do not follow the advise from experienced elderly. I am only 32 years old, but I have learnt it from real life experiences around the society.

However, I believe you understood it and managed to work hard to maintain a level for yourself. Just enjoy the current situation as we cannot get back what we have left out.
