Proverbs

Normally when I am at school I do internet in 2 places. Either I'm in one of the staff rooms or I am in one of the senior 1 classrooms. I like this because the students always leave me alone and I feel I can do my browsing in relative peace.
In the back of the classroom I am currently sitting in I always see a poster that says Proverbs on it. Now up till now I have never actually gone all the way back to read them, but today I did. And after reading them I decided that I had to share them. It should be noted that I have copied the poster exactly how the students have it.

Proverbs
1. A word to the wise is enough.
2.A rolling stone gathers no mass.
3. Traveling thousands of miles is better than reading thousands of books.
4. A friend in need is a friend indeed.
5. One man's meat is another man's poison.
6. Where there is a way there is a will.
7. A great talker is a great liar.
8. You leap what you sow.
9. Actions act more than words
10. A good liar should have a good memory
11. Time lost is never gained.
12. Try and fail but never fail to try.
13. Laugh laugh makes silly.
14. Think twice before you act.
15. Practise makes perfect
16. Knowledge is power.
17. Prevention is better than cure.
18. Nevercross a bridge before you come to it.
19. Cut your cloth according to your coat.
20. Charity begins at home.

Now that you have read them, I think you can agree that it is a little bit amusing. I will admit that some of them are good, but I also have to say that some of them I do not like. Now if you know me, you can most likely guess which one that is(cough number 3 cough cough).
But what can you do?
The only real question I have is who gave them this list of proverbs?
