I think it depends on the person on how is he going to manage his time properly. And if that person is able to manage his time at his convenience.
For sure he can do a lot of jobs as he can.
Especially if hes a family guy and having kids to feed and to go to school.
yeah and not all people can focus with each job, for me better to focus at 1 choice , 1 job, then after succes you can use your money to invest at other place for extra income.
Actually, having a multiple task at a time is tiring, but if you are working on so many jobs for a reason, for sure you can do it all, no need to quit one job for another..Nowadays, working on one job alone is not enough.. Just put in mind to work on many jobs which are at the same field, don't dare try to work as a carpenter and at the same time doing a welding..that's not possible..
I prefer to choose only one job at all to be focus to. But if I'm going to do maybe I'm going to do at very spare time only. Because it is very hard to manage many jobs at the same because you are going to be wasted with it. Even you are a good time manager you only have one body and only one time to use.
Yes you are right health is wealth. Even you have a lot of job but you are going to have health problem because of being workaholic.
So tendency your earnings from all your jobs are going to be use in paying hospital bills.
So it is just going to be nothing.
If you achieved the rich person state of life, youll have the experience and you know already any kind of situations and possible things to happen in terms of business or health. Yes, you reach that point of being rich because your smart enough on making your money grow. as you said rich people is smart enough to leverage other people to work for you. Even your not doing anything your still gaining money which a trully advantage to it even more you have the money to make things undercontrol.
