If you want side income in short order, your best bet is to sell your time (freelancing). Regardless of your profession, there's something to do to make extra income - if nothing else, drive for Uber or Lyft.

If you want side income in the long run, then consider chasing passive income plays where you don't sell your time - blogging, building a bunch of mobile apps or web sites, selling things on Amazon or eBay, etc. These things take a lot of time. Figure out something that intersects your skills, passion, and (a small) market and pursue it relentlessly. Give it a year or two for each idea.
