What does save yourself mean?

[tanyajack]

Betrayal and disloyalty are increasingly common in the modern world. Follow the three-out-of-seven rule. If you have seven secrets, let's say, only tell three of them to your best friends. If you would not want everyone to know about something, do not say it to anyone at all. People change very quickly, and the very person who seemed like your loyal, trustworthy best friend last night could suddenly turn into a ruthless gossip and manipulator the next morning.
