Be assertive but not aggressive. Assertive people are admired and live to persuade again, and again. Aggressive people are told, “We like your passion.” which is corporate-speak for, “We think you’ve lost your mind!”
How can you be assertive, but not aggressive?
Take two shots, then salute. When you have an idea you’re trying to get buy in for, use appropriate strategies and tactics to best increase your chances. If you get turned down, have another run at it. If you get turned down again, salute and move on. You’ll be seen as ambitious, yet reasonable (You can always resurface this idea at another more propitious time).
If you hold on to your position like a hoarder clenches a 1983 People magazine, you’re going to start to hear your co-workers say, “We like your passion.“
