I don't understand your attitude, Esupanitix. Okay, you are quite a bit younger and therefore look at this from a different angle. But still, it is very hard for me to understand what is making you angered here.
Two hours is not a big number, especially when playing something you like. These games were meant to be a past-time activity, after all.
For example, i spent about fourteen hours only playing phantasm, when working for my first clear of the thing. And I didn't get angry, or furious, during it. It was tiring at times, but the outcome was worth it. Or, with SFN, I pushed myself towards ten hours a day, five days a week.
And it only gets better when you start scorerunning. For example, I have almost a thousand IN easy attempts. And that's only a little. I believe my UFO sum will hit at least three times that amount, until I finally reach my target, or accept my failure.
Consistency is something that comes along practice. I have about 1% success rate with UFO stage 3 at the moment, but I'm not mad. Instead, I will get better.
It also makes you improve faster, believing in your targets.
It's all in the mindset.
