"It is a matter of making disciplined decisions via a problem-solving algorithm, instead of responding without thought, thereby making that response a Determined response (Determined = predetermined), One engages a dynamic system that defines the problem by the identification, analysis and prioritizing of all of the variables followed by the manipulation of selected variables (if feasible)"
You need one more step.
Answer the riddle:
Six frogs are sitting on a lily pad. One decides to jump off. How many frogs are then on the lily pad?
The answer is six. The frog only decided. He didn't act. Decisions without actions are the INTP's doom. We tend to be satisfied with having figured out what to do; actually doing it requires what everyone is calling motivation.
Motivation usually involves wanting the outcome that will result if action is taken, as opposed to not experiencing the outcome because no action is taken. Since wanting engages a lot of emotions and not much thinking, we tend to be found sitting around a lot rather than acting. ("Need" engages thinking; "want" engages emotions, so far as I can tell and so far as I can find language to describe the difference. I'm pretty sure "wanting" something trumps "needing" it in nonessential stuff.) ((Obviously I need to eat and I will go downstairs and poach an egg; it engages my sensory equipment to be hungry. "Wants" don't seem to trigger the same machinery.))
I'm winging it here, folks.
