You got to like your work. You have got to like what you are doing, you have got to be doing something worthwhile so you can like it -- because it is worthwhile, that it makes a difference, don't you see?
A joke is not a thing but a process, a trick you play on the listener's mind. You start him off toward a plausible goal, and then by a sudden twist you land him nowhere at all or just where he didn't expect to go.
Horse-play, romping, frequent and loud fits of laughter, jokes, and indiscriminate familiarity, will sink both merit and knowledge into a degree of contempt. They compose at most a merry fellow; and a merry fellow was never yet a respectable man.
Innocent amusements are such as excite moderately, and such as produce a cheerful frame of mind, not boisterous mirth; such as refresh, instead of exhausting, the system; such as recur frequently, rather than continue long; such as send us back to our daily duties invigorated in body and spirit; such as we can partake of in the presence and society of respectable friends; such as consist with and are favorable to a grateful piety; such as are chastened by self-respect, and are accompanied with the consciousness that life has a higher end than to be amused.
