It's tough being set in your ways. Many of us are, of course. Me? I refuse to use a recording device for interviews. I came up long ago enough that tape recorders were unreliable. Too many off my friends lost entire interviews in college that I never adopted the technology myself. The decision to type (see? I moved on from hand-writing!) generally only affects me. I've never been accused of wrongly quoting anyone or anything like that. 

But some folks hold on to old ideas and processes that have a ripple effect. They do things the way they've always done them. Presumably, those things were effective at some time, but they're not now. I've got a client who still clings to ancient layout principles about advertisements in her publication. Even though everyone, including the creative director, show her successful examples of the "new" rules, she steadfastly clings to things she learned in the composition room of her college newspaper internship -- in 1974. Of course, she means well. But her decision keeps the magazine looking a little outdated, and her steadfast adherence to her rules is gradually demoralizing her design team.

As I said, we all have stuff like this. It's human nature. But before you fall back on your default modes today, take a second to think about why you do or think the way you do. Is there a different way that would be more effective? Are you just holding on to the old way because it's comfortable and trying new things can be scary? If you're not sure of the answer, ask your colleagues -- your boss, your successful co-workers. Then set to developing new skills and ideas to help you stay fresh and effective.
