Nowadays, the new concept is becoming wealthy not rich.
It's not just about the money anymore or how fat your bank balance is. There are other resources that are limited that the New Rich (NR) are maximising. Have you ever read 'The 4-Hour Workweek' by Timothy Ferriss? (it's good, sometimes hilarious and can be life-changing).
Time is one of them, so your aim is to earn good whilst having enough time to do what you want. You make money work for you and not you work for the money.
People are doing good at online businesses. But only if you work hard and smart. Find what you are best in (your hobbies, passions, expertise) and tap it into the online world. Money will not come initially but if you do it consistently, you'll see results.
