I myself am a relative newlywed, so, here's a nugget that I could have used: Get yourself ready for the ennui that is going to set in 2-3 months after the date. This has likely been a very exciting year, what with all the planning and anticipation. There's kind of an 'alright, well, here we are, this is it,' thing. Not a very romantic thought, but not a bad thing either. Just understand that the wedding is not a culmination, but rather, a beginning.
