No regrets, just curiosity about where I would be if I had "taken another path." Of course, that's more fun, butterfly effect thinking than it is regretful. I'm happy with who I am at this very moment, and I had a made a different decision somewhere along that long I might not be where I am today-- that's enough for me to see every puzzle piece, no more how dirty, as part of the larger and incomplete picture (thank you captain Picard).
