I’ve been using Linux for the past 5 years, and recently I change from DE to WM (i3) which change it my whole workflow. Now I use a lot more the command line to do even simple things.
Recently I note that some relatives called me ‘hacker’ and I find that kinda funny, may be because I’m so accustomed to the terminal and to i3 that I don’t notice that “it looks like a hacker thing”.
Genuinely I can’t use my mouse all the day, it gives me a pain in my wrist.
Don’t worry, it’ll spread to the rest of your hands soon ;-)
Seriously, take it seriously. I thought I had carpel tunnel syndrome for years but every test pegged it a mild so I got endless suggestions for stretching exercises and no real help… turned out to be my spine.
