The common man splurges too much and doesn't think long term. The investor tries to make financial decisions based on increasing his money over the future.
Not all of them though.
There are a lot of people out there that is not even an investor but they know a lot of things they should do and not should do. To be honest, I don't even know what is the requirements or a classification of a person to achieve that kind of being an investor, can anyone explain that?
