I think it's sort of like the stages of grief, where it doesn't happen in any particular order.

For instance, I know a couple of people who started like the top left (they tend to describe this as their "neck beard phase", who then became the top right. Then they became the bottom left (one is a trans woman, the other still identifies as a man, but enjoys presenting as a femboy sometimes). Then both of them became furries once they had enough disposable income.

I have another friend who started as a furry, but then became the top right when she needed entered the professional world (she was also in boy-mode at this point). Then this made her be miserable, especially because she was even more unhappy in this more conventional mode of masculinity, which made her become the top left. Then her egg cracked, and she turned into the bottom left. She says she doesn't have the time or money to actively be a furry anymore, but she's happy because she has a lot of friends who are, so this allows her to be close to a community that was an instrumental part in her finding herself (also for "helping [her] to not fucking kill [herself] as a depressed teenager")

I imagine that it would be possible for any order of events to work, for different people. And some people may visit certain squares multiple times
