Time is moving really really really fast.
If you are still not aware of that yet, think about last year, last month or even yesterday and realize about how fast time went by to reach the now.
Realize how people, things, situation and environment around you have been changing. Realize how you have changed as time went by.
And time can never stop or slow down a bit. It keeps on moving forward.
How about you? Are you moving forward fast enough to go along with time too?
