A rolling stone gathers no moss

A stone that remains under water gathers moss. But if it goes on

rolling, it does not gather moss. Similarly if a man sticks to a profession,

he gathers experience and becomes an expert in it. But if he goes on changing

his profession, he cannot excel in any profession. For example if a young man

decides to become a carpenter, he should go on working at it. If he works

with preseverance, he will become a good carpenter arter a few years. If he

gives up carpentry after a year, and decides to try his hand at tailoring, he

will become fed up with it after a few months. He will find tailoring very

difficult, and give it up. Then he may try to become a mechanic, and give it

up after a few months. Thus he will become neither a carpenter nor a tailor

nor a mechanic. This proverb emphasizes the importance of perseverance.
