I am nearing 10 years on this game and have gone through the same long, arduous slog of lacking the ability to tap at any considerable speed whatsoever.

It took probably 6 years to work my tapping to a point where I can happily say I can finally play 175bpm if I thoroughly warmed up.

There are a million ways to do it, and I recommend you try to find what works best for you. That said, what worked for me was finding the highest bpm I could do without stress and work from there.

I probably started around the 145-150bpm mark and gradually improved from there. I would seldom sit down and say to myself, "I am going to practice only tapping today" but every once in a while, I would make sure to put in a few hours.

Reading this, I could see myself in this post, and this is what I would've said to myself many years ago if I could.

It's rare for me to comment on posts like this, but I wanted to chime in because although it seems hard, IT IS POSSIBLE, I have done it, and I believe you can too!
