Remember that the brain is a flexible organ. Your neuron structure physically adapts to the demands placed on it. If you have a job, your brain will adapt to become an employee's brain. If you go independent, your brain will adapt to become proficient at that type of lifestyle instead.
My brain would be terrible in an employee's world since I haven't trained it for that. I'd probably get fired within the first day or two for insubordination. I have no proficiency in that world. But if I pushed myself to do so, I could eventually adapt to that situation. And then I'd start thinking like an employee, and part of that would likely include some mental resistance to going independent again.
Your brain will get better at whatever you train it to do. If you want to adopt a different lifestyle, don't continue doing what you've always done. For instance, continuing to show up for your job doesn't prepare you for a more independent lifestyle -- it only trains your brain to become a better employee's brain.
If you feel the seed of desire to change directions now, that seed will likely grow stronger once you start moving. And if you're afraid to change, that fear will soon be overwritten by new patterns, but only after you get moving.
When you commit yourself to a different path, you will not be the same person that you are today. Your brain will reconfigure itself to help you become the person you train yourself to be.
The easiest day for you to change directions is today.
