Sometimes it seems like there’s an app for everything. Yet somehow, new ones keep popping up and selling for lots of money, all the time. If you spot a niche that hasn’t been filled to its potential just yet, and you can learn the coding skills (or know someone who already has them), you could be on to something with this side business idea. Today, it's even possible to build an app without any coding skills whatsoever. Just make sure you validate your app idea before jumping too far in. Even if your app business idea doesn't pan out to be a best-seller, you'll still pick up valuable skills.
To be a consultant, you need to have an expertise in something so you can market yourself as an advisor to others looking to work in that area. Perhaps you managed several large warehouses in your career with a drugstore company, you did all the marketing for many years for a large shoe manufacturer or you set up a chain of beauty supply shops or take-out restaurants. You can use this experience to help others do similar things without making the same mistakes that you made along the way.
14. Get organized. “Organize your files—both in your computer and your paper files—so that everything is easy to find,” Edwards suggests. “The average executive spends three hours a week looking for things—that’s more than 3.5 weeks a year. As your own boss, you can’t afford that. Use color coding for file folders and computer diskettes to make them easy to recognize. Printed labels, which you can create with your computer or a separate label-maker, help readability.”
Another big suggestion is finding small and easy ways to test business ideas and assumptions. I think this is implicit in your post. For example, if you have an idea for a digital course, you may do a free webinar on the same topic first. If you can’t get enough people to show up for a free webinar, then there probably isn’t enough interest for a paid product on the topic.
But it’s also easier for consumers to compare similar products, which makes your ability to differentiate yourself more important. For instance, if you decide to use Etsy to sell handcrafted cutting boards, when a potential customer searches for cutting boards on the site, they’ll wade through potentially hundreds or thousands of relatively similar listings.
