In business and in relationships with others, the most important thing is trust. When someone is telling you about an important event that happened to them, don't try to top them with one of your own. Let them have the stage. Don't worry about not having enough money. Limited funds are a blessing, not a curse.
Nothing encourages creative thinking in quite the same way.
Read anything requiring your signature carefully. Remember the big print giveth and the small print taketh away. Wear out, don't rust out. Learn to recognize the things that are not very important, then ignore them. Don't forget, a person's greatest emotional need is to feel appreciated.
