Do you need extra cash?
Or is that a silly question?
Perhaps a better question is would you like your extra cash to come from an active or a passive income stream.
Do you understand the difference?
You can easily make extra cash from an active income stream.
If you have a suitable motor vehicle, you can sign up with a rideshare company like Uber or Lyft. Depending on where you live, this can be expensive. You will probably require some or all of a special driver's authorization, a permit for your car, a medical examination, a police check, annual vehicle inspections and increases to your registration, third party insurance and comprehensive insurance costs. In fact, you'll probably need special, much more expensive rideshare insurance.
But once you've got past all that, uploaded photos and installed the Uber and Lyft apps on your smartphone, you're ready to go.
Your income is then entirely dependent on how many hours you can spend driving. That makes it an active income stream.
