A few months ago, Bridget Gelms shared the worst professional advice she has heard:
Early-career people in particular are encouraged to take on all tasks in order to prove themselves and — to a lesser extent — discover what they do and don’t like to do. I suspect this is more true for women. I understand why people give that advice, and I understand even more why people take it. But it turns out, saying “no” can do more to advance your career than saying yes.
One thing I’ve observed is that over time, people who say “yes” to every request get a bunch of requests dropped on them. Some of them are good, but many are a waste of their talents. Being able to say “no” when the situation warrants can establish that your time — and thus you — are valuable.
Consider this: you’re asked at the last minute to fly to another continent to be in a meeting with a potential customer for a couple of hours. The potential customer is pretty unlikely to actually sign up, or they represent a small and not-strategic gain. You could go. Or you could find another way for the customer to get the 5 minutes worth of information that you’d end up providing. By not going, you save your company a few thousand dollars in airfare and you don’t lose two days to travel. What else more valuable can you do in that time?
The example above isn’t contrived. I’ve seen it play out, and the person who said no established themselves as someone of value in the company. Of course, you can’t say “no” to everything. Sometimes a task has to be done and you’re the one that will do it, whether you like it or not. But knowing when to say “no” is a valuable skill for improving your career.
