Being an engineer, doctor, or regular employee, are all predictable ways of making a living.
Here if you get a degree and train or study for a period of time, and work for 6-10 hours, you are assured of a certain income.
Then there are unpredictable ways of making a living, like being an author, blogger, YouTuber, or musician.
When you choose an unpredictable path, there is no guarantee that by investing 6-10 hours a day on your chosen discipline or craft you’ll make a living.
Here both downside and upside can be big. That’s why everyone should pursue such a path.
But because it is unpredictable it is smart to add a predictable way of living to the mix.
That way you’ll never have to worry about the basics, while you try to make a success on the unpredictable path.
