66% is the devil point...
I have 6 courses abandoned at 66%..
The greatest power Devil has is not temptation,
It is boredom and procrastination
It is the mid-point sway...

It is the collapse of the pre-frontal cortex,
when we reach half-way through our goal,
when we are too far from our starting point,
and too far from our ending point,
We don't know why we began,
We don't know where we will end.

So the Devil point kicks in at 66% completion,
And makes us procrastinate, makes us feel "meh"
Brave thru it, ye fellow warrior,
Just do the tiniest bit needed in a day,
Just tie your shoes laces and half the race is won
Make a cup of tea.. and the article is written
Clear some clog in the room, and the painting is done..

So, to bump over that comfortable resting point...
that lethargic 66% mid-way stop,
pamper yourself with something momentarily
and just do ONE small thing every day

'Cause I promise you this, when you have inched to 80%
you will be fuelled again with images of victory
all doubt and disbelief and lethargy will be thwarted
You will forget pain and other creature comforts
You will cruise through the finish line..
