Thanks for the comprehensive guide! :)
I just wanted to quickly share two thoughts I had:
A) The first advice contains a repetition: "but it" - you might want to delete one of those.
B) Readers' attention spans are limited - I noticed my attention fading around point 13, so I think it might make sense to condense the content or split this post into parts 1 & 2 or find some other way to keep readers' attention.
Anyway - many thanks again for sharing! :)
