I got pretty good at it, but only because I go on facebook a lot and therefore type a lot
I average 85 WPM while my other friend who has been typing a lot longer than me averages 100 WPM, I'm trying to push towards that speed, but it is hard without me practicing (using actual touch typing testers) and frankly I don't really have the motivation to go any faster, but I shitty accuracy I make a lot of mistakes. But just practice I started out by typing while looking at the keyboard I averaged (80 WPM doing that) once I got good at it, I slowly started to force myself to look at the screen while I typed, of course if it was too hard I would look at the keyboard but I mostly started to look at the screen. Soon I became decent (averaging around 60 WPM). I went on a holiday to Sri Lanka with my Mum, where most of the time I was home alone for 12 hours at a time. I brought my laptop, and I would listen to music and type the lyrics of the song. By the end of the holiday coming home I averaged around (100WPM) when I got home started typing on normal keyboard (75WPM AVG) then got a mechanical (85WPM finally) For some reason I type really fast on laptops, something about the super low keys and soft touch to them makes it easier for me to type. Otherwise with school holidays coming up I might start practicing as I don't really get out of my house as most of my friends are PC gamers and we just game together, I will have time to practice Hope this helps. Sorry for the long read.
TL:DR: I practiced a lot.
