Before you add or change anything, show me a short list of exactly what you plan to do.
Wait for my yes before you write.
Every time you add or change a record, write a short note on that record: what you added, where it came from, and anything you were not sure about.
Before you save a new contact or company, look them up online.
Add what the company does, roughly how big they are, and one recent piece of news about them.
If you are not sure something is true, leave it out.
