"Fuck excuses, learn to admit when you fuck up." This includes trusting the wrong people (and subjecting yourself to abuse). If you never admit you're involved, the same shit will happen to you, ad infinitum.
I think every woman needs to learn to not need anyone and to always always be able to hold herself up alone. Nothing wrong with love of being with a man, just learn to keep your independence! Needing and wanting a man in your life is different.
