There are two ways to create value: Linear & non-linear.
Linear means your rewards are correlated to your efforts, in other words: Your upside is capped by the amount of hours you work.
Non-linear means your rewards in not correlated to yours efforts, in other words: Your upside is uncapped, regardless of how hard you work.
Working in an audit firm creates linear value. Practicing as a lawyer creates linear value. Being a doctor creates linear value. Being a corporate employee creates linear value.
Only equity creates non-linear value.
You can get equity by buying it (on the JSE or in a private company).
Or you can can get equity by starting your own business.
The ultimate source of non-linear value creation is equity in an annuity-revenue business.
Not only can you sleep whilst your equity increases in value, but your business can sleep whilst annuity revenues keep coming in.
Create non-linear value.
