Ingenious v Insane

Defining the sheer fine line between ingenious & insane
Is it a master-stroke of einstein or a madness of the brain ?

Too intelligent almost slipping over the edge
Holding on to the precipice on a dangerous ledge

A wizardry of wonderment is talented indeed
An over-accomplishment that has already gone to seed

Amidst the balance of betwixt  & inbetween
A rose-stained glass or an
even - steven of opaque sheen

An over-compensation
Of clever capabilities
Past the point of acceptable
With over-excessive possibilities

An egghead, mastermind
A wide-awake wide brow
One has lost their marbles tho they don’t know how
