Truth be told, not everyone is suitable to be a business owner. I once started a wine business two years after I graduated from college, with money I borrowed from my parents. Unfornately it ended up as a failure and I have learned great lessons from that experience. Looking back, I actually don't regret on that "experiment" although I lost much money. Now I am living a comfortable life and keep all lessons in mind. It is just best to know who you are and what you really need.
From what I know, getting to financial freedom is not as easy as theory, but it's not as difficult as one might imagine as long as we understand the flow of money (cashflow).
Sourced from several literature books written by wealthy people that I have read, only a small number of them are financially free rich people who take the path of "work, become employees, employees" because they immediately open their business and then set up their business system.
Because the mentality of working for others by giving jobs to others (opening employment/opening a business) is clearly different. And it's not meant to be pretentious or patronizing, just adding and conveying what I know.
So I think you don't have to give up with failure, remember failure is delayed success.
