I think that since most of my work involves typing, my handwriting has gotten really bad. It looks like a bunch of worms...

Paper don't have autocomplete, them ancient technologies

I have the same problem
And my font-size is also very small

But i can say its encrypted by default
OR
Only the worthy can read it

I'm constantly amazed by how unnecessary skill of writing become to me.
If I don't decide to write some personal notes by hand i have literally zero reason to handwrite. Ever.
Not to say it's obsolete skill, but for like 360 days in a year I could probably don't have it and be just fine.
That's some serious mind-f**k right there

My handwriting got so bad that even my signature got impacted

My handwriting was always bad. So one day I decided to relearn it (thanks Jake Weidmann). And it got better and better. It really is fun to write in university with ink and my handmade penholder. I use the Spencerian "font" btw.
Yeah, I'm weird... But that's ok.
