Any advice that assumes it will fit everybody equally is advice to avoid in most cases. On the other hand, the best advice I have ever been given is to not listen to anybody for advice as it is tarnished by their own experiences.
My mother never believed me. So, here's me. The eldest of three. Three thousand miles away, and pulling my hair out because I'm the oldest and their safety is my responsibility and I can't reach them. Forever. Jeez that's depressing. Yes, I see somebody. They wanna send me to DBT to teach me how to get around these hang ups. But those aren't hang ups - those are my sisters.
