When you start to make money with your eBook publishing company, which you'll invariably begin doing if you follow a proven system, don't flaunt your wealth. There came a point where I was making about triple my usual salary thanks to the money I was bringing in with my eBook business. What would have happened if I showed up for work driving a $75,000 sports car when I was earning less than $10 per hour?
Here's the bottom line. You should really try to minimize the amount of time you spend with trial and error and just follow the lead of others who have "been there and done that." You'll really speed up the amount of time it takes to start being successful so you can finally quit your job once and for all.
