A year ago, another user mentioned Monero so I looked into and discovered it's more "bitcoin" than Bitcoin and bought what I could.
I'm not a millionaire, but it sure has helped me financially, so I'm really appreciative that I took advantage of that opportunity.
EDIT: and for something a little more intrinsic: Everyone's experiences on different things. I've read lots of great comments on raising kids, and hope to take advantage of that shared knowledge when I have a family.
