How do you spend weekend?

I spend my time with reading a book,
browsing internet for collecting info,
and writing this blog this weekend.

I read one book titled "Be adult with childish mind"
by iPhone.

This book is published as an iPhone apps and
we can find easily the book now.

This is written in Japanese and
 English version is not published yet.

I hope they will do the publishing in the near future.
 In this book, he says that adult people
 who make something creative never forget the childish mind
with no exception.

He does not say that we have to be child because we're grown up as time goes.
But childish have to be kept in our mind and never be adult.

I'm very confused by this because being an adult is pretty much what people want to be and will be.
What's wrong with being an adult?

When I look up a dictionary for the definition of "adult", it defines "a person who is fully grown or developed". Being an contrast, child is developing.

I didn't fully understand what he's implying in this book but I made a guess.

An adult person is developed and fully balanced.
There is no space left for development.
This means that a person does know every convention and
 common sense for life and he or she will live under this dogma.

From the perspective of creation,
dogma is the enemy that must be removed from development
because creation always comes from something uncommon and out of scope.

Being an adult equals to finished creation and development.

What people will be after they finish creation for life?
.....just waiting for the time to dive into the grave?

It might depend on how people want to live their life
but creativity will expand the possibility of the solution
of problems that we're facing in a daily life.

This book encouraged me to live my life in a creative way.
