I have a new client that I am doing some mentoring for. I think that I love this more than any other form of billable work.My mentoring clients are mostly companies that are just now getting started with .NET, so with my nearly 3 years of .NET experience and a bizarre memory of many resources ("oh yeah, I remember there was an article on that by so and so last summer"), I can really help VB6 developers leapfrog past a lot of their learning curves for the specific tasks they need to do (including planning and architecting the program).  I really really enjoy doing this. Getting paid for it almost feels like a bonus.
