Decision making

Kids always hope to be an adult some day~and of cause they will become one.

To be an adolescent- a process in between childhood and aduldhood, is a real amazing part of life where and adolescent may get:-own room, hand phone, computer, credit card, etc, which are things that if one is too young to possess one, may not have their own possession. However, the more things one possess, the more burden is on one's shoulder, one will have to bare more responsibilities, which means that one will have to learn to take responsibilities seriously. What one does, have to bare the consequenses of there doings.
Is this also called a fun thing? Why do kids ever want to be an adult? That's the most idiotic ambition to have.

The older one grow, the more decision one have to make-and that is call part of the process to be an adult. If one think that he/she does not want to make decision at some point of their life, just to enjoy the moment of their life before they step into the next level of their life, he/she is called an irresponsible person, which is trying to be an ostrich.
Is that so?

Of cause, making decision can't be like just a click on the delete button, and can dissappear from ones life. It never can be! Even a very small thing like:you wan a strawberry or vanilla flavoured ice-cream?which have to be made by a kid. That decision will be made by just following your heart, picking the choice that you like.

As one grow older, however, he/she will of cause have to make such simple decision, but, there are some other decisions that can't(is not possible, but human can make anything possible, right?) be made by following what ones' heart tell one to do. Here is where brain come into function. Brain, starts to analyse things(which may make a simple matter become rather complicated) and make decision, which is accepted by the society, which is scientifically called "relative etiquette"-such that even you yourself don't really agree to the decision you made, but "the society say so". That's the thing!!social aspect of life.

Things grow complecated at older ages, because brain come into function.
What if I still make decision following my heart and not analysing things using my brain. I will be called a "20-year-old kid" or an irresponsible person.

Should every one in the world have the same point of view? I mean, does everyone have to do things, only following what ones' brain tell them to do??
