I might want to make even these decisions emotionally rather than rationally, unconsciously rather than by conscious thought. Conscious thought might not be the most efficient use of my brain.

Also, do I want to devote all the energy I would need to answer these questions, now? I use a QWERTY keyboard, it seems good enough at the moment, Why? Well, why not?

However for practice at being rational with that conscious thought bit of the brain, this is a useful exercise.
