Cool thread. I'm not sure if I can narrow it down to once specific "thing" - but here are a few off of the top of my head: - A high quality pair of noise cancelling headphones. I use the Bose QC35. They're great for tuning everything out and either enjoying your music or focusing on work if you want. If you fly somewhat frequently, these are a godsend for tuning out plane noise and enjoying music/movies. - A really high quality bed - a little while ago we splurged and bought one of the Heavenly Beds from Westin. It's seriously amazing, for me at least. Now everyone has their own preferences when it comes to sleep/comfort, but my larger point is that sleep is so important and you spend so much time doing it that its wise to invest in something high quality that works for you/your partner.
