Good times don't last; they end too fast.
Good aromas linger only for a moment; bad ones stick.
Good feelings precede bad ones.
Good people are the few among the bad ones.
Good men don't necessarily get good things; bad men don't necessarily get bad things
Good decisions are hard to come by; bad ones are easier to make.
Good memories don't stay; bad ones do.
Good things, you can't hold on to; bad ones, you unwittingly do.
