Every month, my Sifu sends out a monthly lesson. Each lesson contains an assignment to be done by each student and returned back to him by the end of the month. This was my response to his assignment: "Write a paragraph explaining whether you feel you have enough time in your day, and why."
Do I have enough time in my day? Hmm, well from a purely scientific point of view, I have 24 hours - the time it takes the Earth to rotate 1 revolution around it's axis. I physically can't have any more time no matter how much I demand (or think I need) it. I also can't have any less time. We all have 24 hours in a day - no more and no less.
If you look at the usable time in a day, the time you have between waking up and going to sleep, that is totally in my control (what an illusion that is!) but still limited by the 24 hours in a day. I can get up really early and go to bed very late, or even stay awake for the entire 24 hours, but that would catch up to me eventually and I would have to sleep.
In reality though, it seems that there isn't enough time in the day. It seems there is always something to do and seemingly never enough time to do it. But, that is less to do with not having enough time in the day and more to do with not using the time we all have efficiently. And that is an entirely different question.
I'd like to share my favorite quote from The Hitchhiker's Guide to the Galaxy: "Time is an illusion. Lunch time doubly so."
