8. You Can't Do It All Yourself

Some entrepreneurs have a superhero complex that they feel they can do everything themselves or with just one co-founder. They think that it's possible to scale the company with just two to three people. This just results in being overworked and unfocused. Know when to bring in people that are often smarter than you are. By bringing in others to work with you, there's also ability for each team member to be laser focused on what they're best at.

9. There Is No Such Thing As An Overnight Success

In some cases you may be able to find out that your idea just won't work or that you are one of the lucky few that get acquired early on. Other than that, be prepared to work on your startup for many years. The press often makes it seem as if success happened overnight, but the entrepreneurs themselves spent a lot of time with the company over the course of many years. Startups aren't a 5k, but an all out iron man competition.
