It is painfully obvious you know absolutely nothing about creative people.
The word "creative" is not reserved for only those in the arts.
It has broad strokes of meaning which cross all professional boundaries.
No one knows that better than Mihaly Csikszentmihalyi.
For 30 years, the man has studied what many would call "creative geniuses."
I will cut to the chase and tell you the most common denominator is they are all, paradoxical in nature.
From Mozart to Einstein.
This is why I laughed out loud reading your ignorant post.
Yes, I can indeed imagine a person who is not only smart/accomplished but also acts child-like in nature.
That's exactly what the most creative people in the world are like.
To come up with anything innovative, regardless of industry, one must indeed be creative.
The number one person who comes to mind which embodies the creative personality is none other than Albert Einstein.
He was smart, accomplished, and yes, child-like.
Clearly, you have no undertanding of people.
To put it bluntly: Your thinking is pure slop.
Clean it up.
