I've been working for the last few months on a project that uses five (count em, five) different databases. It's taken me a couple of months to line up all the data (I usually end up doing the initial "data grinding" on these types of projects, since I like doing SAS work). We finally got initial some results, and they look pretty good - everything we expected to be statistically significant, was.
So, I can relax a bit now - all that time didn't go to waste. So I think I'll go celebrate with a long bike ride.
