Happy belated birthday! This year was definitely your best gift I love the idea of doing some event to celebrate...although I have yet to switch over to that from the "buying something special" plan.
One of the best event celebration things I've ever heard of was some friends who decided to attend 4 different operas in NYC over the course of a particular year. They are huge opera fans and it was a 3-4 hour drive for them so it was perfect.
I don't care if you are or are not traditional, but I do LOVE your approach to creating the life you want....along with embracing those extra little plans that God makes for you according to that saying....:-)
