lessons in friendship

I've read Stan Toler's book - The Secret Blend. Let's see if I can remember the ten lessons in friendship:
1. like yourself or be a friend to yourself
2. if you want to have friends you have to be a friend
3. be a good listener (that's why you have two ears and only one mouth :))
4. encourage people
5. learn to forgive
6. it takes some good chemistry to make a relationship work (that part is slightly mysterious but you can influence a reaction right?)
7. bring out the best in people (that's a direct derivative of point 6).
8.
9.
10. teach others the first nine points :)
