Learning KBM is way easier than I though it would be

I thought for years the move from controller to mouse would be too hard so I just put it off. I just got bored a couple days ago and decided to do it anyway. It took me around 2-3 hours to get used to it, I have better movement now than I do on controller. My aim is not as good yet but just within a few hours I was able to run around and get kills and such.

I am an above average controller player, and I've read apparently part of your skill could transfer over. So maybe that's part of it. I've also used computers since I was a little kid I just never played a game with a mouse.
