I find these videos to be what I experienced as typical Jordan Peterson ramblings. A clearly above average affluent, above average intelligence speaker, who goes off with what feels like very little preparation or direction. Does very little for me, specially when it comes to the specific topic of "taking time to think things through" that i was inquiring about (but also anything else, really).

Well in the second movie he explains what happens when you set goals without much thought.

It could be it is not your thing but I believe he has some authority when it comes to psychology.
