I think that this might be the most valuable piece of advice that I can give to anyone wanting to increase their credibility, gain respect and take charge of their career. And it’s simple too:
BE ON TIME
By the way, arriving right at the minute the meeting starts is not being on time. Get there a bit early. Figure out the seating that’s best for you. Get your laptop fired up and your papers in order. Order your coffee, check your email, get your head together.
Let the other guy be the one that arrives in a flap, apologizing for the traffic. Smile and be gracious, all the while knowing that you have acted like the pro in this situation. On time shows respect, it builds your personal brand, and it puts you in control.
