This is why it is advisable to go with your own business, no one will set the rule for you, no body will tell you why you didn't come to work early, why didn't you close at this time, the problem and stress of working with a company will give you nightmares till you retire. On the other hand, if you have your own business as an entrepreneur, you will decide what you want to do with that business, you own your time and what you like to do and how they have to be. Having your own business is the leading goal right now.
Keep in mind, that if you work at the office and you dont have any task to do, with high variability you will get your salary. But as an entrepreneur, or being your own boss, every time you dont have task, every time you do nothing, every time you open YouTube in search for funny video or this forum, you are loosing money or is one step closer to bankrupt. Even if you have finished your working day and having a rest at home, or sleeping, you are loosing money. Always remember that.
