So what's your work scenario? Do you go to a workplace or do you work from home or on the road? Are you more productive from home or the office?
I go to workplaces. Two part time jobs. One packaging job, one cleaning job. The first is in the morning, the second is in the afternoon. I do not work from home, nor from the road, so I am productive only on my workplace.
Two part wines jobs probably brings some diversity and interest I guess. I know someone who makes a very good living working three jobs; own part time business and two part time jobs. She makes a lot of money and is kept engaged and interested.
