Starting a business isn't for everyone, and it's not what you should do if you aren't sure what else to do. It requires thick skin and the willingness to carry a great deal of stress, sometimes alone. It's more often a life of failure than a life of success, and the majority of successes came after a long road of disappointment, and often shame.

For almost the first year of The Muse's life, I would do 5 to 8 networking events a week. And I don't necessarily think that's the right path for everyone, but I realized that as an entrepreneur, one of my strengths was finding the right people who could help us. I didn't come into startups with any network.

If you're able to arrange a trial period with a new hire, do it. It will give both of you a chance to make sure the position is a good fit - and can help you avoid being in the awkward situation of wanting to fire someone three or four weeks in.

Even your most talented employees have room for growth in some area, and you're doing your employee a disservice if the sum of your review is: 'You're great!' No matter how talented the employee, think of ways he could grow towards the position he might want to hold two, five, or 10 years down the line.

One of the top causes of startup death - right after cofounder problems - is building something no one wants.

I am a big advocate for having an open discussion about team norms and preferences. At The Muse, some of us like to start working at 7:30 A.M. Others focus best from 10 P.M. to 2 A.M. Create a culture where it's acceptable not to be working when someone else is working.

Launching a start-up, you need to get a lot done quickly. Every day is different. Everyone pitches in with everything. It's easy for the founding team to say, 'We're flexible. We all help out with everything!' But when it comes to making decisions - that flexibility can spell inefficiency and disaster.
