Have more than thou showest, Speak less than thou knowest, Lend less than thou owest, Ride more than you goest, Learn more than you trowest, Set less than you throwest, Leave thy drink and thy whore, and keep in-a-door, and thou shalt have more than two cents to a score
Came across these ancient but true to date lines of wisdom in a sixteenth century book – King Lear by Shakespeare!
Following is my humble (and a tad bit sarcastic) attempt to rephrase these lines into modern day english.
Flaunt your possessions less, Speak your ignorance less, Neither a borrower nor a lender be (unless it is your calculated profession) Work harder than you think necessary, Don't bet on luck, Don't be a slave to addictions and expensive hobbies, Save, save, save your money, That way you'll have a retirement nest egg!!

George Frederick Bensell
