From The Mediocre Upwards - The Usual Procession

Experimental, experience, expertise; 

There is ease in expertise. 

From youth to adolescence,

From the mediocre upwards,

From the in-un-non-experienced

To the experimental, ignorance

To knowledge:

That’s the whole of it.

The rest is in the eye of the be-wholder.
