Track Your Own Patterns

Grammar slips matter most when they confuse your listener. Mixing up "he" and "she" leaves people unsure who you mean. A wrong preposition ("interested on" instead of "interested in") sounds off but rarely causes real confusion.

So keep a personal error log in your phone. Each time you catch a repeated mistake, write it down with the correct version, and review the list once a week. Most learners find they trip over the same handful of patterns again and again.
