[Pseudo Enigma]

when I used to play (lol wrists):

1-60: Ignore like the plague
60-70: play once every like 6 months, try to AAA if I land on one by chance.
70-80: warm up, try to beat my PA from the last time I played
80-100: concentrate, PA, not really concerned about combo. Work on my weak points by practicing certain files.

I never really was concerned about AAAing, but whenever I tried I never was able to do it. So it's definitely a whole other skill to practice.

edit: another good thing to do is play for a bit (2-3 days), take a break for a week or so, and come back. Take it easy.

as for actually playing the songs and hitting arrows "when they should be hit" is by dividing the song into chunks, and playing them while thinking of those small chunks. I also try to only watch yellow and purple notes, as those are the most common notes in most stream. This helps me subconsciously deal with the reds, the blues, and the oranges without thinking about it too much.

getting into the beat is also another good strategy. You're less likely to miss notes if you do.
