Thought I'd share a simple budgeting tool I used to help alleviate/delay the inevitable monetary stress. I first decided how much of my savings I was willing to spend on the sabbatical. I then divided that amount into three buckets. The first was small and was my fun bucket (I think mine was b/w $3-$5k). I worked my ass off and it was time to have a little fun. The second bucket is the oh-shit-its-time-to-get-a-real-job-again bucket. I assumed it would take me at most 3 months to find the right job, so this bucket equated to 3 months living expenses. That leaves the remainder for your "core" second bucket. When I was spending from this bucket I never once thought about what I'd do AFTER the sabbatical because I knew I had that covered financially. I simply focused on the sabbatical itself and had an amazing experience.
Good luck and have fun!
But, if you have some time to explore then don't jump on the next nice looking boat. Date the next four or five interesting projects lightly until you're sure one is the right fit.
