05 - THE ART OF BEING SLOW -or not

No, I really don't like having a limit to do things or doing when everybody else does them just because it's "the time" to do it....
A childhood friend reminded me of this today, she said: oh yes, because you are reserved, quite shy.. -said after not seeing me for two years and knowing nothing about me since seven....
Anyhow this made me realize of how our society is full of this things: for example, those who aren't the typical type person from that age are seen as nerd, shy, dumb, idiot, stupid, immature, old way of seeing things, etc.
What I do believe is that every person has its own time and can do whatever they want whenever they want! -yes, it's shocking when you know that someone who's 19 is having a baby, but maybe they chose it and wanted to be that way.. it's also shocking that somebody else being 19 also, has her own shop.. or many others.
We, all of us, set things to ages, ways of being, of thinking, of doing, of anything.
If you do something before the time limit it's "because you grew faster than all the others".
If you do something after the time limit it's "because you grew slower than all the others".
This is what you can find at any place, any time and in any way. Posters, flyers, shops, concerts, television, etc, etc, etc.

And who sets this limits? Who's doing that? Or else is somebody changing that? Does anybody know? Is somebody really controlling this time-age limits? Who? When? Where? How?
