Again (Einstein's Insanity)

I've done it again.

I've gone 

And put my foot in where

I ought to have refrained.

I tried my hardest

And yet failed.

I gave my love

But it proved vain.

I trod ground 

Where armies quailed

And braver men fell

While women wailed.

But nothing ventured,

Nothing gained

So I went at it

Unashamed.

Now I find,
To my dismay,
And despite lessons learnt
Along the way,
That pushing on 
Against the grain,

I've gone and done it 
Once again.
