What "adult" means?
Why losing our soul is named "adulthood"?

There are mature children;
As there are immature adults;
and vice-versa.

Being mature begins with not being ashamed for living and declaring what makes you relaxed and happy.

Suit and tie won't make you an adult nor give you success, necessarily.
Loving art, culture, the nature and the things that relaxes you won't prevent you from being an adult and successful.

Being an adult shouldn't prevent you from being a child.
As being a child won't prevent you from keeping your adulthood!

If you want to make this world better, you have to "forget" it first (a bit).
Take your pink pill to leave it (before you react mirroring), get different, creative, and powered up then come back.

Only a somewhat innocent and humble mind is capable of learning better.
And what makes us alive and successful is always exploring, experimenting/trying, learning and building "legos" in the life; as the biological/chronological children does.
