I knew Ilya Somin when he was single and striving to find a good match. It took a couple of years, but I was over the moon when I got invited to his wedding. Now Ilya has two precocious children with his wife, Alison. In this guest post, Ilya shares the main lessons he learned from his experiences as well as relevant research. Enjoy, and if any of this proves useful (or to avoid confirmation bias, useless or counterproductive), please let Ilya and me know.
