Repetitive gameplay - the ultimate test of willpower we've all failed many times.
The failure comes when you look at the clock and realize you've spent the last four hours attempting to get through this one small stealth section that you haven't been able to beat without getting spotted.
At that moment, something breaks inside, and you find yourself in tears or throwing your controller - maybe both. You suddenly try to remember a moment within the last four hours when you were consciously enjoying yourself, and nothing comes to mind. This play session has been mind-numbing, so you turn off the console and walk out the room, telling yourself you're done. Forever.
Fast forward about twenty-four hours and there you are again, at your wit's end, trying to get through that damn stealth bit.
Your controller survived your rage and is back in your sweaty hands. You fail once more and feel yourself giving up again. But something stops you from quitting.
You're not sure what it is, but you decide that you're going to give it one last go. And somehow, you actually manage to beat the level.
The relief washes over you and you feel your strength returning. You are a certifiable badass.
