Let your work show beauty and perfection, we are not just here to earn but to learn as well.

This statement is inspiring.

You've said a lot, and honestly it's one thing we writers need to learn. I get those issues too; when I'm reading a content and I find such errors, and trying to guess what the writer actually meant, I tend to lose focus of the idea. I've had my share of errors too, I would wonder how that skipped me. Sometimes it's when I read again after posting it for some days I discover some errors, and truly I feel bad.
We're not perfect, we're not machines but we can always do our best to bring out the best possible. Those tools you cited are very important; especially grammarly for me.
This is a needful and necessary post, and you did justice to it.
