Dear 65-year-old Christina,
In honor of my 100th blog post and the reflection that accompanies every good vacation, here are some thoughts to consider about how to spend your retirement.
FYI, you're too old to be a geisha and you don't like camping enough to be a legit lumberjill, but I think you have a real chance to become a stained glass artisan (consider mosaics, too). Maybe focus on amazing stained glass valances, like the one above you saw during the drive back from Hayward, and specialize in themes inspired by your Japan travels, i.e. cherry blossoms and the like.
Also, please fill in the gaps for any states or continents not visited (feel free to skip Antarctica). And, master something more sophisticated than When the Saints Go Marching In on the piano. I'd love, love, love it if you took on violin too.
Your 30-year-old self
