I was involved in large project. It involved making three web integrated web apps for five different companies. One company managed the AD integration, another did the phone system components… there was a lot going on.  

Nine months in when the project was looking ready to fail, the lead client wrote the following email – an elegant piece of inspirational genius:

Client: This is simple stuff, why can’t you just make it all work?

Later on he wrote less pleasant emails, but they’re too obscene for me to post here.
