You want to be a millionaire
If you ask any millionaires, they will say that was not their ultimate goal. They simply love the freedom of making choices and doing things on their own terms. Focusing the "millionaire" status as the ultimate goal may cause you to lose focus on your core business and you will constantly change the nature of the business when the sales are slow or the profit is insignificant to your target.
You want to spend more time with your family
Quitting your job so that you can spend more time with family is a noble intention. However, in business reality, working time is not certain and you need to work overtime during the first three years of operation.
