For my talented and industrious

colleague Helen Wylie, who was there when

this book was born.

Many ingenious minds labour in the throes of

invention, until at length the master mind, the

strong practical man, steps forward…, applies

the principle successfully, and the thing is done.

Samuel Smiles,
Self-Help, 1862
