Christmas letters for my husband ideas please help!!

For Christmas this year I decided with my husbands gifts I would add a personal homemade one for him from me but I’ve been struggling!! I wanted to write him “read when…” letters, put them in a box, and gift them to him. So far all I have is read when you want something relaxing and read when you want something sexy. Either I can think of another “read when…” idea but am not sure what to put/write in it because I don’t want them to all sound the same or I can’t think of any other simple “read when…” ideas at all. Please help give me some ideas as if you were doing this for your significant other and something’s you might say to help me spark some creativity!! Also gifting money isn’t really an option as I’m a SAHM and he makes and keeps all of the money so it would basically be asking him just to gift it back to him. TIA!! ❤️🎄
