Do not tell anyone you're going away for an extended time, even if very excited about your trip.
A friend, neighbor, or family member visits your home every day to clean out your mailbox of mail. There is nothing that can deter burglars more than the sight of a pile of mail.
Be sure to inspect all locks that are in your office and at home. If the lock appears shaky or worn-out to you, it'll look similar to an intruder, so have it repaired or replaced as soon as possible.
