Contrary Proverbs II

The best things in life are free but there's no such thing as a free lunch;
Slow and steady wins the race but time waits for none;
Do it well or not at all but half a loaf is better than none;
Doubt is the beginning of wisdom but faith will move mountains;
Great starts make great finishes but it isn't over till it's over;
Practice makes perfect but all wodk and no play makes Jack a dull boy;
Silence is golden but the squeaky wheel gets the grease;
You're never too old to learn but you can't teach an old dog new tricks;
What's good for the goose is good for the gender but one man's meat is another man's poison.
