Biggest lesson from the days where I was the only technical person in our company: Get a monitoring system in place that you trust. Then get a second, completely independent one in place that you trust. Then also get on-machine monitoring (monit, et al) that tries to fix things if they go bad. In retrospect, that should have happened a lot earlier. Once we had redundant monitoring systems and a firm belief that if something was down that I'd be notified about it, the world became much more chilled out. If I didn't have an SMS, the services were up and running.
