Every self-employed person has to develop certain habits and tendencies if they want to generate enough income to keep up with personal and corporate financial obligations. As your own boss you are the only person standing in the way of your own success. People who own and operate businesses for long periods of time tend to develop attributes like punctuality, diplomacy, reliability, diligence, and frugality. As an employee of another company you simply don't have the burden of responsibility that a self-employed person does, so you're never pushed to adopt such traits.
