If any young man wishes a set of rules even more concise, here it is:
Get into a business you like.
Devote yourself to it.
Be honest in everything.
Be cautious. Think carefully about a thing before you act.
Sleep eight hours every night.
Do everything that means keeping in good health.
Don't worry. Worry kills more men than work does.
Avoid liquors of all kinds.
If you must smoke, smoke moderately.
