My brother had the total opposite problem where his thumbs were too big for the keyboard so he kept hitting two letters at once and sending texts that looked like a cat walked on his phone. He tried swipe typing for maybe three days and went right back to pecking because he said it kept guessing the wrong word and he got tired of fixing it. I gave swipe a real shot for about two weeks and honestly the thing that killed it for me was typing names or slang, it never knew what I meant and I'd end up deleting the whole sentence anyway. Now I just use one thumb and hold the phone steady with the other hand and somehow that fixed most of my typos. Weird how the simplest fix is usually the last one we try.

Your wrist hurt for 3 days over a cake. Is that really a win? The cake came out fine, sure, but you basically made the job harder on yourself just because the old mixer felt familiar. A stand mixer is not some mystery machine, you slap the paddle on and turn it on, that is the whole learning curve. Next time just use the new one and save your arm.
