The Efficiency Test
I subscribe to the Bow Tied Bull theory for structuring your career. Get into sales/programming/finance, and max out your income. From there, build an online income source that is 2x your monthly income. Once you can do that for 3 months in a row, you need to quit your job and do this full time.
To break this down for me, this means I would be making over $60k/month to quit my job. Double income is a crazy thing.
It is crazy to me that in todays day and age, this idea is not only feasible, but others out there are hitting these numbers as solo entrepreneurs and those with small teams.
What a time to be alive.
