While starting a new business can be exciting, you'll need that #ideajoy to carry you through the more mundane tasks of business operations. As a solo-preneur, guess who's wearing all the hats in the business, from product design finance, marketing, & beyond? (Hint, hint: It's all you, baby!)
Focusing on ideas that give you personal joy will lead to greater & faster success in your business. Between career & family, many have only their precious free time to build a new product or business. You'll be more likely to stay dedicated to a heart-felt idea well after the initial excitement wears off.
