Six of Crows- Chapter 21 (Leigh Bardugo)
Busy life, isn't it?
If Kaz is seventeen, and joined the Dregs in twelve,
he'd have five years to PLAN and achieve all that. Except he wasn't arrested since fourteen,
so unless he fucked up big after one of his big targets already done, we have three years only. All while gaining trust of his boss and co-workers, making a name for himself, recruiting useful people he needs to get to know first and organizing such endeavours as rebuilding a whole fucking harbour, when already owning at least a part of the Crow Club?
This is a world of liars, merchants and cheats. It should take some time before he establishes himself enough for others to be willing to deal with him in a way ALL the risk won't be on his side.
Kaz allegedly managed way too much in a way too short time.
He either should've been written as older, a child from already established family or have an admitted supernatural time-managing skill alongside his superbrain and miraculous amount of luck. Not even being a prodigy guarantees success. Just look at the amount of failed "gifted" children on this hellsite.
He's so "lucky" he's hard to take seriously as an underdog he's presented as. If he can do so much with so little in such a short time without memorable setbacks, he "doesn't have it so bad".
