I could tell ya about carpal tunnel and how to get really bad quickly and regret that for 30 years?

You're talking to the wrong guy for any of that stuff. I suck at games and play them on easiest settings any time it's available. I consider difficulty in games a personal insult to me from the developers with one glaring exception of anything from FromSoftware except Dark Souls 2.

Different games and genres will have different ratios of luck / inborn talent and reflexes / research and training. But over time I've found the best way to get value out of games is to not care how good or bad you are and just enjoy the ride of seeing something new or doing something you just can't do in real life.
