Growing old is mandatory while growing up is optional. Actually, this is a metaphor which said that you should always focus upon giving your best at everything that you do!
This is because life is too short and thus, you have got no other option in hand but to live it to the fullest.
You need to understand that it is not by the years that we live, but the life that we have in all those years. With each and every passing day, we are bound to grow and we cannot restrict it by any chance.
We ought to realize that growing old is mandatory and you cannot escape it anyway. You cannot prevent your growth and the age will go on increasing day by day.
However, make sure that you are growing up alongside. When we say, “growing up,” we do not depict the years that we live, but we imply the things that we do in all those years.
One needs to understand that we need to grow up, but it is rather about the lessons that we catch up in all those years.
You will definitely grow in terms of age, but is that enough? Definitely not! Your real growth is not determined by the age, but by the experiences that you have, and you can have them only when something has happened to you.
Try to start living your life and focus on inculcating lessons from each and every single day. Grow up and you shall see things changing around you all by themselves.
