I really like the ship metaphor, it works on a lot of levels. Disconnecting from the big ship and rowing on your own is scary, hard work, full of unknowns. You might get capsized. For other people, they can happily get towed their whole life and never be unhappy. It's sort of a curse that some people get so upset with the big ship that they can strike out on their own, but it's also a blessing to manage to find that opportunity.
