What if I'm not good at self-reflection?
If you're not good at self-reflection, it means that there's a lot more in your unconscious than you know. This is the stuff we don't want to look at. So it's good to find somebody who knows you, or a few somebody's who know you. That can be relatives, that can be past boy or girlfriends, it can be good friends of yours. Ask them, honestly, what they've seen in terms of your behavior over the years. The more information you can gather about yourself the smarter you can be about your future choices.
