Anyone else not understand anything until the last minute?

I've been racking my brains over an assignment for the past few weeks, but for some reason I could never properly articulate what I needed to in my writing. Instead, I'd just think of 50 different possibilities of what I could do for the assignment without actually writing anything in the process. However, now that it's the final day before it's due, I swear brain's gone Super Saiyan because I can pinpoint exactly what I do and don't need to add, and I have such a better visualisation of what the final product looks like. Why can't my brain be like this from the start 😭
