Last time that he went on a big vacation, I gave him a sketch book/journal, colored pencils and some pens for him to document his trip in.
I keep thinking of something that maybe he can read daily... something about seizing the day and making the best out of life, but not just a letter... maybe a little book of notes? I don't know...
He was in a motorcycle accident last August, so it'll be a year since it happened, and he's learned to just appreciate life that much more.
Thanks for any ideas!
