My first company failed completely. And it failed at about ten months old. I had about 12 months of savings, so when it failed I was thinking: 'Do I go back to work?' And at that point I believed so deeply in what I was doing that I couldn't imagine anything else other than trying to make this business work.

When you start a new company, you have to do it all. Yes, all of it.

Most weeks, I work 100-plus hours on TheMuse.com. There are definitions of 'work-life balance' that would say I have none.

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.

So many of my rookie mistakes could have been avoided by first-hand exposure to other, more experienced technology entrepreneurs.

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.

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.
