If you want to be your own success, then you'll definitely have to work, and a 9-5 job is a great way to grow and learn.
9 a.m to 5 p.m job is great and I think the standard hours of working. Eight hours for me is not too short and also not too exhausting, it's just in the middle so workers can definitely do their job in maximum efficiency. It was a good thing also in a sense that you still have a sufficient time to bond with your family everyday and visit/manage your business. However, in our country, you will be triggered and get mad because of the heavy traffic every day. It eats your leisure time, imagine the 2-3 hours of travel you spend after you go home. That really s*cks.
