The things I found most helpful about ivyexec.com are their webinars. We need to adapt to new trends in business all the time. Everything from writing resumes to behaviour changes constantly, so I need to stay up-to-date. I usually get the information I need through those webinars and I consider them to be a "must watch" for every serious businessperson. I'm also thinking about having my own mentor and ivyexec has a lot of them so I won't have any problems in choosing one.
