They say Life and Death are not in anyone's hands.
They are things that just happen every time and with everyone. Same is the case with time. Most of the times we take it for granted that there is always plenty of time. Due to this perhaps we indulge in various activities, which are a wholesale waste of time.
The clock is always ticking. The seconds keep on ticking just like busy ants. The ants keep themselves always busy by always hunting for food everywhere. Similarly the seconds always keep on ticking to attain short-term goals of making a minute with 60 ticks. After reaching a milestone of a minute the second's hand of a clock don't take a break, but start afresh for another round of 60 ticks. The take it minute by minute and inadvertently reach a quarter of an hour, and hour and then a day. They always focus on the smaller targets- that is a minute and the bigger aim of the clock itself gets fulfilled. That's why the minutes hand have to work less, as the seconds hand does most of the running around. The minute hand just has to make 60 movements on a clock dial. The hours hand is the luckiest of the lot. It just moves for 12 times in an hour. But the seconds hand movies for 3600 times around the dial for the same hour!
Parallel to this, in our life to we never realizes that we have lots to do. Between every big task we can always find enough time to fit in a plethora of smaller tasks. If you are waiting for a train at the station, you can always read a magazine or rather chalk out your study timetable for exams. While traveling in the bus too one can find enough time to at least skim through the previous days notes.
Be like the clock. Always keep on ticking by involving yourself in various things and learning new things. These small knowledge and experience modules will perhaps one day take you to your bigger goal some day. They say "Time and Tide waits for no man". If so, now stop staring at the screen and utilize your time effectively!
