This is mainly about creating your own wealth. The first basic question is how do you want to spend your time? Since we are creatures of habit, having a scheduled 9-5 job with someone else directing you can be very comforting. It takes a special kind of person to go off and schedule your own day, work hard towards a goal, all while fitting in your normal life in between. With a job, you are forced to go to work at a set time, then when it's done you go home and continue your life for a few hours. Not everyone wants to spend that time creating wealth.
Depends on how you define rich. It's all about income and expenses. The millionaire next door typically doesn't live in a massive house with extravagant cars.
Salary plus commissions can get you $250,000 a year as a sales person with little experience if you are willing to work hard and can handle rejection.
Do you have a recommendation on what to sell? How hard is hard? Can I work medium hard and earn $150k? Do I have to live anywhere in particular? Do you have to travel 100+ days a year?
