Intelligence and motivation are separate categories, anon.
Motivation is the master of reason, not the other way around. If you want to improve your reasoning, improve your motivation.
I was actually kicking back and forth some enlistment options with the recruiter. 10 years out of service, but a return is not impossible. Then it hit me that I may fit in rather well with the 35 series MOSes in the army.
I left because I felt that the uniform was becoming an obstacle to proper service of the nation/constitution. My motivations have always been to restore the U.S. to its constitutional constraints. It is something I would forsake all other things before.
I may be a flawed individual and prone to my own bouts of 'ree' at things - and be far too hot headed for normal politics - but the oath I took was to the Constitution and I take it seriously.
