Everyone should have more than 1 stream of income - why? Because you should never depend on the money you earn from just one source or unreliable employer.
What might happen when your employer decides to move location, cut operating expenses, pursue new lines of business or simply downsize, outsource or 'right-size' the company?
Another income can be earned without demanding more than a few hours a week of your time. You could invest those extra dollars into a retirement account, purchasing a second home, building a larger source of income or any number of things.
Many people have turned their hobbies and leisure activities into abundant stockpiles of cash - do you like to do crafts, train animals, entertain others, take photographs, write poetry, etc.?
