Hitch your wagon to a star.

We were fortunate to hitch our wagon to Phil early and he hasn't disappointed.

You are doing your best only when you are trying to improve what you are doing

We do what we can, and then make up a theory to prove our performance the best.

Don't be too timid and squeamish about your actions. All life is an experiment.

We do what we must, and call it by the best names we can, and would fain have the praise of having intended the result which ensues.
