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.

When talking to first-time entrepreneurs, I often ask them: 'How do you know that people want your product or service?' As you can expect, the answer is often that they don't yet, but will know once they launch. And they're right. That's why it's critical to launch as quickly as possible so you can get that feedback.

As a kid, I always idolized entrepreneurs. I thought they were cool people in the way that I thought basketball players were cool people. It's cool that some people get paid to dunk basketballs, but I'm not one of those people.
