Don't read what you've drafted (first draft) that day or the previous day's work. Just move on. Finish the draft first.
And reading yesterday's draft pages will only result in you fixing spelling, punctuation, and syntax errors. This is a huge waste of your time. Most of those premature fixes will be wiped out or no longer appropriate in later drafts. This is because you will move, add, cut, and totally rewrite most of your manuscript. So that typo you fixed on page 56 of your first draft may mean not even appear in a subsequent draft. But it was correct before you cut it. All those tinkering fixes are best done after your second or third draft. This is because by that point you have everything that is going to be in your final draft, you have cut everything that needed cutting, and you have moved what you felt needs moving by that point in the process.
