Just heard about a book about “portfolio careers that’s scheduled for release in 
mid-October. The theme is that more and more of us bypass the single career option. Instead of working in ONE field for ONE employer, we now find ourselves working multiple jobs for different employers.
The book claims to offer a 10-step guide. I plan to review the book (if I can get it) but I have a few ideas of my own.
(1) Make sure that you are not creating a conflict of interest.
Employer A is a bank. They say you can’t work for banks or financial institutions.
Employer B is a dogwalking service. They say you can’t start your own business within 1 year in the same neighborhood.
Now you know you can work for A and B, but each job has restrictions. Get any info on restrictions in writing and be aware that (a) some unwritten rules may apply and/or (b) some written restrictions may be illegal or unenforceable. I am not qualified to give legal advice so you would need to talk to a lawyer who understands these types of laws if you have any question. Unraveling a conflict after the fact can be expensive.
(2) Choose careers that are synergistic with each other. If you have two jobs that call for writing, you may be exhausted. If one job calls for sitting at a desk and thinking, while the other gets you moving and talking, you may be refreshed and energized. I like to say some jobs are yin and some are yang; when you get both, you have a good balance.
