If you have your own business, it is possible to improve your business with intelligence and planning, and the improvements you make will improve your own business. In a salaried job, no matter how much talent you put into your job, the improvement you get will be the improvement of someone else's business. At the end of the day, if you are laid off from your job, where will your position be? You have established a business yourself, you are the owner of that established business and you will never be afraid that you may be fired from your job.
Exactly, if you have business have possibility increasing earning more higher than how much paid from earning salary as worker indeed you have been much experienced worker but your earning salary keep stable. Based on earning salary not matter how limit your working and push all your capacity but earning keep stable not increasing yet, difference when owning a business you have chance increasing earning more than earning salary but have risk with your business collapse.
Both of kinds earning salary and owning a business have advantage and disadvantage, if you want push limit and increasing your owning have try with owning business but if care or worry about risk so take your self from earning salary become the worker. In my opinion better owning a business because have chance to get financial freedom than push limit working at the other with stable earning salary month by month or not matter how many years have worked.
