This is really useful! And I do agree, there are a lot of people who might need to take a second look at what they write, but I do recognize that I have problems as well and I definitely got something to think about from this :D

Everyone makes mistakes, it's just what happens. I just hope that people stick to the small mistakes and not the punch-worthy mistakes.
Despite everything that I've put here, my writing's a mess before I've proofread my work XD
