Nobody said that getting into the interactive marketing game would be easy. You knew you'd face challenges, obstacles and even some dissension.

Still, there are days when you think, "I never expected this!"

We asked some veteran brand marketers to share some of their "what the…? " moments, as well as what those lessons have taught them.

If you're a marketer just starting to dip your toes in the space, take heed:

We asked:

1. What one thing do you wish someone would have told you when you first got into the interactive space?

2. What's the best piece of advice you can offer a marketer that is "green" to interactive? 

Our veterans:

Kevin Doohan, director, interactive marketing, ConAgra Foods
Sheryl Biesman, internet marketing manager, Nature Made
Correy Honza, director of internet marketing, Quiznos Corporation
Bill Daley, interactive marketing manager, Universal Orlando Resort
Gary Peeples, internet marketing manager, Black & Decker
Glenn Broderick, executive director of gaming, AT&T

If you'd like to share your advice, answer these questions: What's the worst mistake you ever made? What was the outcome? What did you learn from it?
