I can relate to this. I'm one of those people who usually had a little too much work to do, but still felt bad when no one else volunteers for a task. Often I'll offer to take it. I'd end up enjoying work less & less and got a bit disgruntled until I was back to my base-line of work. I definitely see it as a weakness in me, but also in my manager who let it happen. As I got older, I started to work at around 90% capacity and grab a tea or chat with a colleague or do some admin for the remainder. This enabled me to jump on to urgent requests and even make extra efforts like physically walking over to discuss the matter. This also enabled me to look out for junior colleagues who seemed a bit stressed.
