I also discussed how I got a side business going. But that wasand quite a bit has changed since. Where a side business was once a novel idea, it has since become much more mainstream. Make lists every day of things that you might enjoy, and try to figure out how you could make money doing. Most of these can be done at home in your spare time, and in your spare space. See if there are any ideas below that fit you. Have a meticulous eye for detail and love to get things gleaming clean? Auto detailing is probably a perfect side business for you. In essence, your job is to make cars sparkle inside and out — and many people are quite happy small companies that make a lot of money pay well for this service. Got lots of evenings free? Like kids? Babysitting may be a great side business for you. Keep an eye on multiple children on Friday and Saturday nights and you can earn some easy cash over time. Have some extra space in your home?
