If you're someone who aspires to write well some day, I think it's worth drawing a further distinction. /u/blueyes might agree with this:

"I do not believe that many people will ever learn to write well, unless this person believes learning to write well is worth the effort. If someone doesn't want to learn to write well, it's not worthwhile to make them try."

Which means that if _you_, reader, want to write better, it's worth trying to do so.

If you don't want to write better, well, you've not read this far, so don't worry about it.

edit: grammar x2 It's not easy to write clearly.
