Give people more than they expect.
For instance, if someone asks me to provide them with some data, I’ll email it over to them, but I’ll also throw in a little note with a few related links that may also help them with their project. I’m pretty good at finding things online, and it doesn’t take me very long. For my extra two minutes of work, I may save them 30 minutes of additional searching. And even if it doesn’t help them this time, they’ll remember that I gave them more than they asked for, and that I’m a really helpful girl.
