"Franklin’s Four Rules for Living
It is necessary for me to be extremely frugal for some time, until I have paid what I owe.
To endeavor to speak truth in every instance; to give nobody expectations that are not likely to be answered, but aim at sincerity in every word and action – the most amiable excellence in a rational being.
To apply myself industriously to whatever business I take in hand, and not divert my mind from my business by any foolish project of growing suddenly rich; for industry and patience are the surest means of plenty.
I resolve to speak ill of no man whatever, not even in a matter of truth; but rather by some means excuse the faults I hear charged upon others, and upon proper occasions speak all the good I know of everybody.

Selected Quotes of William Thomson, Lord Kelvin
"In physical science a first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. I often say that when you can measure what you are speaking about and express it in numbers you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.
