I beg you to not push yourself too much. I pushed myself a little over my limits of playing standard! and taiko! maps. I can see why getting +97% acc on easy maps will help improve. Playing hard maps are always fun but I had learnt that if we push too much RSI will come. I had learnt a valuable lesson.
A tablet pen, and a few keycaps. osu! doesn't really make me that mad, because if I break my combo it's entirely my own fault, while in other games I get frustrated at other players (even though I can't say I'm much better than them myself.)
