Want to boost your career? Say ‘Thank you’ more than ever before.

That was the message at a San Francisco International Association of Business Communicators event I recently hosted where the theme was managing our careers in a VUCA (Volatile, Uncertain, Complex, Ambiguous) economy.

Yes, there were exhortations from our speakers to use LinkedIn better, build our networks before we need them, become specialists, and work the system tirelessly.

But the most important message? Practice the personal touch.

Show your passion – it will be compelling. Be vulnerable – ask for feedback; if you don’t get the job this time, ask what you can do to be better next time.

Send hand-written thank you notes – put a stamp on a letter! If you send a thank-you gift, do some research to learn what the receiver really loves.

There are myriad ways to say thank you — but say it more and more. Expressing gratitude can be the most powerful thing you do in a VUCA world.

I can’t say thank you enough to that evening’s great speakers — Rene Siegel of High Tech Connect, Brad Whitworth of Cisco, and Beverly Butler of Wells Fargo. Thanks. And thanks again.
