(As an example, this still happens, even now: Just recently, I spent 4 months working on a business idea with my team, spending a huge amount of time and money, until we ultimately concluded it wasn’t worth it. We shelved it away and I wrote an email to the team, telling them, “We can’t figure out how to make this work. We’ll re-look at it in 2 years.”)
Best of all, unlike a brick-and-mortar business, you don’t need a lot of startup capital. In fact, you can get many internet businesses up and running with no money at all because so many free services facilitate the possibility. For example, you can set up a website or blog for free using WordPress. Or you can leverage a third-party site like Amazon or eBay to sell goods with no inventory costs. You use their selling platform in exchange for giving them a cut of your sales.
