I usually don't make enough eye contact with people, so I tried the eye contact exercise described by Nick Winter, which involves pairing up with someone unfamiliar and gazing into each other's eyes for 15 minutes. This was just a week ago, and I already noticed mild improvements in my ability to maintain eye contact. I haven't yet noticed anything as dramatic as described by Winter or Luke (who did a much more intense version of this exercise, starting over when eye contact was broken), though to be fair both accounts sound like the effect did not get noticed immediately.
"Eye contact" is a misleading term. People who say they want more eye contact don't mean they want you to look at their eyes for extended periods of time. It helps to move your gaze to a different part of their face every five seconds or so.
