These bumper sticker adages are a reaction to the rich wisdom that proliferates our highways. It's better to halfway do something than to not do it at all. Don't finish something you never started. The day after yesterday may come sooner than you think.
Arms are for defending.
The rich are first draftees into the war on poverty. There's nothing like nonexistence. It's always now. Poor hygiene is next to Atheism. Don't count your eggs before they are fertilized.
