Side hustles continue to be all the rage. While about one third of Americans had one in 2020, 40% of Americans are dabbling in a side hustle in 2022, according to a May 2022 Zapier survey of 2,032 U.S. adults.

People's reasons for picking one up vary: Some do it to make some extra cash, others do it for the pure enjoyment of whatever their gig is. And for anyone looking to sharpen the skills they use in their 9-to-5, starting a hustle could help with that, too.
