This means you have an LLC for a single business activity, which is filed correctly, has an Operating Agreement with clear and precise terms, you set up a separate bank account for that LLC and its related business activity, you do not use that bank account in any way for personal activity, and while it varies per state as being a requirement, you always want to make sure you have periodic filings and to take it even further, hold a "meeting" once a year...even if you're the sole member and there's not much changes that took place for the year.
