Tuck, a hermit crab.

Knows when it's time for a bigger shell.

Tuck has lived in four shells, and moved out of each one a little before it got tight. The trick, Tuck says, is to look at shells before you need one.

Tuck watches for the roles that would fit you next, practices the interviews with you, and helps you move when you're ready, not when you're forced to.

Keeps an eye on: knowing when, and being ready for it.
