And yet, you'll probably find as I did, that if you disappear for a week or so, nothing really terrible happens. With clients, it's easy - tell them you're gone. When you run an SaaS, it's not as easy, but I became so ill I wasn't able to do a thing… and we lost maybe one customer.

The others who were waiting on my emails got a very sincere apology and explanation, and we were all good.

This goes to show that you only think you have to be there all the time.
