There comes a time when a person needs to make a conscious decision to let go of baggage. At the same time, though, you have to figure out what you will bring into your life to fill in the spaces left behind.
So, when you're at that middle point, when you've decided what (and who) needs to be left behind, but haven't decided what to bring in to your life, what do you do?
You wait and observe. You observe your own behavior. You observe what brings joy and what does not. You set standards f0r yourself. You back away from people who are not meeting your standards. You start to live according to your standards. Water seeks its own level; who you are is who you attract.
You learn to become comfortable with who you are, not who you were. You start to make plans about who you want to become, where you want to go. You ask questions, you seek answers. You learn to be patient.
But it takes time. Perhaps a lifetime. Perhaps all the questions never get answered. It's OK. Being willing to take the journey; being willing to step away from what might be comfortable but not right, is worthwhile.
