To answer this, I have come to believe that S's (mostly SP's, IMO) do not "look into the future" as much as N's do. There's a lot of that being discussed in the "Ti constructs" thread. ISTP's, as an example, just think (Ti) about the "right now", whereas, INTP's are probably better at seeing what effect an action will have on the future (i.e. what consequences may come out of it). My ESFP brother has done some things that really made the rest of the family scratch our head in disbelief - things where he totally acted on impulse and clearly did not give any thought to what would result from his actions. He has shown some amount of regret, but not in the way most people would. His approach is basically, "it seemed like the right thing to do at the time. Besides, we were having fun. It was awesome!"
If something is really enticing to the senses and to his impulses, it's almost as if "the sheer awesomeness of the moment" is all that he considers. He just dives in and goes for it. And if it doesn't turn out well, then he just deals with the consequences later. He digs himself out of it then. But, he's still going to enjoy the awesomeness of the moment.
I've said things to him like, "You put others in danger and what I really don't understand is you put your own life at risk. You could have died doing that!" He'll just say, "If it's my time, it's my time. But at least I enjoyed my life to the fullest."
That really seems to be the mindset of the SP's.
