This used to upset me, but as time goes on I'm more excited about it. Sometimes I run into someone else that only does that one or two things. They are happy they finished them, etc., but they seem envious of being able to do lots of things even if they don't end up mattering.

Ya sometimes it feels like a missed opportunity, but I think it's mostly just ego and not anything of real value. On the flip side, I feel like I've gained an incredible amount of diverse experience.
