Be smart enough to know when to stand up for yourself and others. Don't let anyone walk all over you. People think they can play with fire and not get burned but everyone suffers the consequences of their actions eventually, just remember that.
The older I get, ;the more I realize the value of privacy, of cultivating your circle and only letting certain people in. You can be open, honest, and real while still understanding not everyone deserves a seat at the table of your life.
