One of the truly great rewards of doing a fine job on a legal project or deal is receiving an email from a partner that says "Thx" (note that writing "Thanks" is inefficient and eats into billable time). When you receive such an email, cherish it, because it won't last long. Before you know it, you'll receive an email from the same partner saying, "Pls hdl asap" and you will then be at square one needing to earn another "Thx."
