Some people replace the word "season" with "szn" or the word "please" with "plz." Not all sighted users will know what those spellings are supposed to mean, and many screen reader users won't, either. Many screen readers will read "szn" as S-Z-N and "plz" as P-L-Z.

When using Microsoft Word or Google Docs, don't just make text bigger and bolder to make it a heading. That will work for sighted users, but screen reader users will miss that and just hear it as normal paragraph text. Use actual heading styles, like level 1 through 6.
