I used to take training but now I just hire a consultant for a couple of days. My problem is that the need for training arises when I need to achieve specific goals, I have the option of spending £1k or so for a weeks training in which I get taught completely irrelevant (to me) things or spending £1.5k on a knowledgeable consultant who will help me get the job done and tell me the pitfalls - there's no contest there, I get more achieved in 2 days with someone who knows what they're talking about than I do in a week in a classroom.....

I do suffer from a lack of a breadth of knowledge sometimes, I think, but then if I learn something in a classroom that isn't relevant immediately I tend to forget it within 3 months anyway....
