I'm a business owner for the last 15 years... Well, I'm 33 and have never worked for anyone in my life. I own a toilet hire company.
There are many businesses out there that do things that you don't pay attention to, that make heaps of money. Also, look at things that most people don't want to do... There in lies many opportunities. Like a previous post said, look at providing things for "lazy" or time constrained people. People are trying harder and harder to save time. Think of something that can do that.
Also, how about starting an Uber? You could even drive it yourself say, God forbid, you're let go at work. I believe it's possible to clock in R8k to R15k a week depending on area obviously. Uber takes 20% of that.
