Selling your time by the hour will not get you ahead.
Most people don't start their own business; they create a job for themselves in addition to which they have to function as boss, secretary and marketing person--four jobs in one, a burnout track rather than leverage.
Not everyone is cut out for such stress, strain and uncertainty, and this makes a job working for someone else at a reasonably secure salary look pretty good.
To be sure, you will work hard in order to get rich, and the harder and smarter you work, the better your chances. As my dad would explain, "It's okay to work eight hours a day for someone else. Just work eight hours a day for yourself too... and twelve hours a day on the weekends." And that's exactly what he did, all his life.
