"Wisdom is knowing what you don't know."

Maybe:

- The author is has a very acute sense of where his expertise is limited and that fact leads him to seek really expert help when he needs it?

- He has spent his time gaining deep expertise in an area rather than trying to spread his time across a number of unrelated?

- He works in a team where he doesn't need the skills he's listed?

- He's just modest about his capabilities?
