The best advice I've ever given, but never followed:
Being lost is okay.
I know you feel hurt and confused, but what you find when you are lost is often worth much more than what you'd discover staying on the same path and never questioning what lays just beyond. Sometimes we need to wander, to take a risk, to follow our hearts into the dark underbrush to find the little treasures of an untapped forest.
Though the path seems to guide is in the right direction, the path only guides us in the direction that others have gone before.
