The most popular side hustles for millennials are "home repair/landscaping" (12 percent), according to Bankrate. A total of 9 percent of millennial respondents make additional money babysitting and 8 percent selling or reselling goods online, including via sites like Ebay, according to the survey. Other millennial side gigs include substitute teaching or tutoring; doing hair or makeup; earning money by finishing online surveys or completing tasks for people online; or doing freelance photography and videography (4 percent each).
If you have the gift of gab, public speaking is a worthwhile side business idea for you to pursue. Many authors, medical practitioners, scientists, artisans, politicians, and other subject matter experts earn extra income by delivering speeches, seminars, and presentations. Professional motivational speakers earn an average annual salary of around $90,000 with just that portion of their income, making this a very realistic side business idea while you continue practicing your craft.
What I really love is the level of granular action-taking. Sure, there’s enough theory to explain why something is important, but the real value is that the book gives you something very specific to do every day that moves your quest forward.

I surprisingly get a lot of people asking to detail their car. I never intend to make a business of it, but I love doing it to my cars and people ask me to do it to theirs.
