One key to wealth is freedom, you are not being restricted to a particular place for a period of time like people that work a 9 to 5, and you can do whatever you like whenever you are pleased, this is one of the benefits of being self employed...people who work under someone don't really work for themselves, they work under someone and do the tasks and activities the person requires them to do and they get paid in return for their services rendered
You got some point here but when you say some good approach to wealth is freedom, I will want to get your point, is it in the aspect of one being versatile in what he or she does or being able to get some contacts and business plans personal and act on them with our being restricted by anyone, although being caged by employee is one of the easiest way to get poor, is just like knowing your worth and being paid peanut for same, people stress out themselves while working for an employer that stagnates their growth by making them feel that he or she is paying them much while in those employers mind, they are just playing with their intelligence because they know that they are actually doing well but wouldn't want to say it out so that they don't see reason to think otherwise, although the truth is that people should learn how to start saving once they get a job no matter how small and never have the mindset to work in a place forever to avoid being stucked.
