We're talking about the short term results here. The goal should be to win the money in the long run, so you should be more focused on improving your game than how much you won/lost this session (which is exactly what OP is talking about).
Of course the results do matter in a way that you should review the hands where you've lost a lot of money to find leaks (although you should of course review other hands where you've won money as well). But when we're talking about being result oriented we mostly talk about variance.
If you were results oriented, winning a lot of money would mean that you are good. So if you were on an upswing, you could think that you're doing good, not invest time into reviewing and learning, and then face reality when a downswing comes and destroy your bankroll.
You should worry about results in the long term more than in the short term. If you're losing for half a year or a year, you're probably doing something very wrong. But if you've just lost a lot in one session or two, it could either mean that you are actually spewing a lot, or you could play perfectly and still lose 10BI in PLO for example.
The problem with poker is that the result of a hand/session rarely tells you much. For example, if you have a losing session you could have been card dead. You could have been unlucky in a way that you ran into the nuts with 2nd nuts all the time. You could have had a couple of bad beats. Or, you could have actually played terrible. The number of money won/lost in a session won't tell you any of these things. Reviewing sessions, posting hands in hand evaluation forums, coachings, private coachings, sweat sessions and strategy discussions will.
I think a lot of people actually have motivation in form of competition, being the best, etc. If money is primary motivation for you, you're in big trouble... Money alone won't bring you happiness. Motivation can be found in things that you need money for, like financial independence, freedom, health or helping people, but in money alone, you will only get limited motivation and a lot of frustration if you start losing it.
People play poker to win money, and then do some stuff with that money. Some people play just for fun. Some people like challenges and want to improve thier game so that they could for example win a sunday million. There are many different things that you can play poker for... Sure, money is one of them. But it won't get you all that far on it's own...
You can simply not care about results by reviewing your game frequently and trying to improve and fix leaks. If you play well and keep improving, results will come eventually anyway ;). Poker isn't a game where you could force winnings in the short term. You can't decide to have a winning session. That's why winning money shouldn't be your short term focus, but long term focus. And for that, you need to have your short term focus on improving your game (and should never stop doing it).
At least that is my point of view... I'm not saying I'm right or wrong, but that is how I see things. If anyone else has a different view, enlighten me :).
