There is a lot of great anecdotal advice here, but I have more questions... if you are still participating in this thread that is....
You said you are hating yourself for still being a slave. Why is that? What is wrong with working for someone else? You know, when you have a successful business, you will have to answer to far more people and have far more responsibility to yourself and others than you do right now with a boss right?
So in knowing that, because I am certain you already did since you sound like someone who is going to achieve a lot of success. What is it making you hate providing value to a company and getting paid? What could change that? (is it possible you have a certain expectation of yourself or maybe someone else like your parents have an expectation of you, that you are not meeting?)
Also, who is it that you see yourself as? If you are not there already, are you on the path to becoming that person?
So to answer these in order...
1) Why am I hating myself for still being a slave?
Because I am being instructed on how to deliver value. My company is very old school, uses ineffective tech, and is inflexible in considering others' ideas for improvement. They hired me specifically as a business process analyst, yet when I lay down my recommendations they are met only with objection and claims that the efforts to change are too steep. It nullifies my motivation to try.
2) What is wrong with working for someone else?
Basically, no ability to scale income. I may train myself to be better at what I do, provide more value to internal customers, and so on. But no matter how hard I try and how great the results I create are, my salary lives in a "pay band" that dictates the maximum amount I can make.
3) Do I know I would have to answer to others beyond just a boss?
Yes. I do not mind having many accountable parties, as long as expectations are made clear and agreed upon upfront. What I do mind is being accountable to someone who does not value my efforts beyond checking a box.
4) What is making me hate providing value to a company and getting paid?
The thing I hate is that I'm not paid for value. I am paid for checking bureaucratic boxes, such as spending X amount of time at my shitty desk, making sure I schedule and conduct meetings that only serve as a means to waste peoples' time, making sure I produce documentation of my work - rather than producing the work itself, etc. The company defines value the way most people would define waste and/or suffering. It is being paid to control risk and maintain mediocrity, instead of being paid to take risks and incrementally improve a product or service.
5) What could change that?
This is one that really made the gears turn, and I'm still not sure I have a great answer. Since encountering MJ's books I have been singularly focused on finding a way to enter a situation where I am in control of the value I produce, and making sure I am producing premium products or services. Two years later, and here I am. Still standing at the drawing board. So perhaps the thing that can change that is an evaluation of my approach to entrepreneurship. I have a tendency to focus on what I know / what I'm capable of / what I don't know. I think it may be time to stop focusing on myself. This is new to me, and weird, admittedly. But I'm thinking perhaps if I focus on others, I can mold myself to meet their need. Then it doesn't matter what I know, it matter only that I know enough to satisfy what they need me to do. The hardest part is maintaining this mindset while being asked every day to do the opposite.
6) Who is it I see myself as?
This answer will be dark and transparent. I see myself as someone who was once a fighter jet and is now a crop duster. I was an all-american athlete, helping my collegiate track team win one championship after another. I was a regarded researcher who used to produce insightful and valuable information for academic audiences. In contrast, I am now an order-taker who despises their existence. I am a shell of what I was before leaving college. My confidence is diminished. My sense of purpose is absent. I am aimless in mission, and a ball of anxiety. In my current state, I am valueless.
7) Who do I see myself becoming?
The vision I have for myself is relatively simple: an autonomous producer. This entails setting my own parameters for work, controlling who I sell to, controlling who I work with, controlling where I do my work and when, and controlling the values by which I conduct my business and my social behavior.
The path between what I am now and what I envision as my "ought self" is hidden from my view. Perhaps it is as simple as finding a problem and solving for x, but the past two years I've been incapable of doing so. I think what it will really take is patience and commitment, which I need to work on a lot. I have a lot of respect for others that have made this transition, and my hope is to model their growth in some fashion.
