If you have a friend who is veering off in what you think is the wrong direction, resist the urge to tell them what to do. Sometimes, the best support you can give to someone is to let them make their own mistakes and learn their own lessons. Plus, you shouldn't get involved with stuff you are unsure of, even if you think you'll be helping out someone you care about. You could end up making it worse for them. It's time to switch the focus back to your own life.
