Samuel Smiles：Thrift, Excerpt 164

Watt, also, when inventing the condensing steam-engine, maintained himself by making and selling mathematical instruments. He made flutes, organs, compasses,--anything that would maintain him, until he had completed his invention. At the same time he was perfecting his own education--learning French, German, mathematics, and the principles of natural philosophy. This lasted for many years; and by the time that Watt developed his steam-engine and discovered Mathew Boulton, he had, by his own efforts, become an accomplished and scientific man.
