Nobody learns how to judge value in school. Your family didn’t teach you that either.

It’s very important to have a good sense of value to detect opportunities. If you can see through the surface (appearance, cash) you may find out that a person can give you opportunities, opening doors, sharing contacts, finding jobs or projects, helping you make money and/or have fun.

Who should have more value to you? Someone that can give you one thousand dollars, or someone that can show you how you can make ten thousand? It is obvious but most people will choose the former and ignore the later.
