As tempting as it seems to wear tennis shoes with your tux, don't do it. I think it looks ridiculous. If you're 14 years old, maybe give it a shot. In general, don't portray anything that says 'I'm too cool and I don't care.'
Don't organize for any other purpose than mutual benefit to the employer and the employee.
Since the generality of persons act from impulse, much more than from principle, men are neither so good nor so bad as we are apt to think them.
