@neologist,
I believe in being half way ((at least)) half way mentally sane before moving forward, proceeding.
That thing where understanding, reading directions/instructions, understanding is a must if you want to succeed.
Oh?
as I slightly turn my head to the right.
I need to know how to fly the plane before taking off. What buttons do I push, what gear do I shift, etc yes you need knowledge even if it's a small amount.
