Your comment about being "successful" in a career caught my eye. When I got out of the Army 50 years ago, I went to work for a big corporation. I noticed that I could get along with about 80% of the workers, 60% of the first line supervisors, and about 25% of the department managers. I concluded that "success" would require advancing among the ambitious, greedy, vain, and others of low character. This was not an environment I would prefer and decided to chose a different path than "success".
Even in the social sphere what is defined by banter, and skill at schmoozing seems only to mask the relational poverty of our society at large. Those who lack skill swimming in these waters or for one reason or another find themselves on the fringe, are in an interesting position. From this vantage one can observe those others who also do not fit well into the modern social milieu. This is a perspective that allows one the freedom to identify and help some of the others.
The homogenizing effect of TV and school have presented us with a monolithic view of society. however, there is greater diversity than we have been led to believe. If we find it difficult to connect with or advance in the world that has been described to us, we may find that operating as an independent agent allows opportunities of which we were previously unaware.
Once we can shed the idea that we need to find a place in a world that doesn't fit us, we can begin to build our own place and it can actually be enjoyable. If you have a dream about your own business, you might want to make sure it is based on what you enjoy. Since most businesses fail, a lack of success will not rob you of what you like. You might want to avoid the trap of seeing money as the measure of success or worth.
There are powerful forces of collectivism that work against the individual competing in the marketplace with a product or service. However, this is not new. Even in medieval times if one choose to work outside of a guild, they would face serious trouble.
If you desire to start a business, you may first select the type of business you enjoy and then get a job working for someone doing that business. From the inside you can learn all sorts of valuable information that can improve your chances of success should decide to go it alone.
