I like to say that “being an entrepreneur is really sexy … for those who have never done it.” The reality is that it’s lonely, hard work, high pressure and filled with mundane tasks. It’s a gritty existence. In the grand scheme of things no matter how hard you work and despite your appearance on the TechCrunch50 stage no one seems to really care. That next round of investment is proving difficult. Customers are harder to sign than you want. Journalists have just written an article that wasn’t favorable. Your competitors just announced positive news. You’ve got 8 weeks of cash left and one of your employees just asked you to fill out a form so she can buy a house. Tenacity is about pushing forward every and not accepting “no’s” while resiliency is about taking punches every day and not falling down.
