I think you're missing the point, Victoria. He's asking if it is harder to do that now, as opposed to some time in the past. Perhaps you have less patience, or less time, to grind than when you were a thirteen-year-old.

I certainly have less time to play games. It's not harder for me to complete them, it just takes more time (not in-game time; but I'll be playing one game over a longer period of real time -- months instead of weeks, for instance).
