If the perfect thesis exists, it’s not yours. No corrections is not a reasonable goal. If you’re not asked to do any corrections that doesn’t mean your thesis was perfect. It doesn’t mean that there’s anything “wrong” either.
Do some work, get some feedback, talk about it in useful ways, repeat a lot and do something that amounts to a significant, original contribution.
Chasing perfect is a way to drive yourself crazy. Make something that matters.
