Reason #2: Wayne has already conquered rap. He should try conquering another field, too.
It would selfish for us to sit here and tell Wayne to keep rapping and forget all his other interests. And, from what we've seen, Wayne does have other interests. From skateboarding to fashion, Wayne has lots of interests. So, why doesn't he give himself the chance to fully immerse himself in some of those interests for awhile? Who knows? Maybe he'll be a huge success in one of those fields, too. Once upon a time, no one thought he'd ever be considered the "Best Rapper Alive," and look what he did when he put his mind to becoming that.
