So you're the boss now.
All-knowing and all-powerful. The wisest of the wise, the noblest of the noble.
Well, no. Not really. You're the same person you were yesterday. Just because you are sitting at the head of the table, and people lower their voices when you speak does not make you wise.
Wisdom comes from learning - by reading, by doing, by making things happen, falling down and getting up again.
A title never made anyone wise.
