If I am being honest, creative naïveté is exactly what you want starting out with any type of creative endeavor.
Singing. Painting. Writing. Anything.
Because if you had any idea – any real idea – of how hard the task was going to be, you would never start.
So I say start young if possible. And work as hard as you can for as long as you can.
Get comfortable with the practice of it!
In the long run, it’s also incredibly important to know your why.
Why are you doing all of this in the first place?
Riches? Fame? Critical acclaim?
Is this a task that you want to make part of your life even if you are terrible at it?
Even if you “fail” at it?
If so, then you might be on to something.
Despite a lack of natural ability, I did have the one element necessary to all early creativity: naïveté, that fabulous quality that keeps you from knowing just how unsuited you are for what you are about to do.
