Yeah, for some reason I struggle with just playing slow. I think that means I tend to overestimate my skills by playing faster than I should with my current skills. Or I think if I just play the same stuff often enough (even if it's too fast and thus seriously wrong), I think I'll improve faster? So therefore, I need to play as fast as possible to get more reps in the same time in as possible?

It's probably like when you go to the gym, you shouldn't just bench press your sets as fast as possible and completely ignore your posture, lol
