Get a job and you'll outwork your competitor

Getting a job is a superpower.

Only if you don't fall into the trap of living paycheck to paycheck.

If you want to learn marketing,  get a job for marketing for a year and implement all that you've learned reading books on that subject, and now you're better than the guy who only reads books on marketing.

Once you're done getting on a certain level in that skill, switch to a different job to learn a new skill.

Do this whilst you're building your own business.

In this process, don't run for the paycheck. Remember your main goal, it's learning.

Over the course of 2-3 years, you'll learn enough to quit that Rat Race and succeed in your own business.
