Many advise to write not when you are young but when you are old, for in the wisdom of age one ought to share his mind.
My advice is to write a little when young, for in writing you encase and keep safe the innocence of youth, like a treasure chest of gold locked away for the following generations.
The mind of innocent youth is angelic, it is ethereal, and aired with the auras and atmosphere of heaven.
Closer to reality, in union with divinity, innocent youth have within their minds the perception of truth that is from above.
