That's good advice. Unfortunately though I think the nature of support is that on average it selects for the more difficult people in your customer base, for the same reason that doctors spend a lot of their time with hypochondriacs (despite hypochondriacs making up a small percentage of the population). Something that helps to offset this psychologically, and is also a good thing to do anyway, is to proactively reach out more frequently to all your users. It can be the case that 95% of your users are happily chugging along, while 5% are unhappy and complaining frequently for whatever reason. If you rarely hear from that 95%, it can start to irrationally feel like no one is happy with your product, since that's the message coming from most of your support interactions.
