The Different Stages of Adult Development

I'm somewhat skeptical of like developmental stages just because I think you can, you can often like learn things at different times and then it's kind of more about what you're interested in. There is something like a logic of the situation or a like background knowledge that you'd need to have for them this step to make sense. So, yeah, maybe,. but if you think of stages as more like what makes sense to come one after the other or like, at what point in your life does this thing become relevant, then yeah I'd be on board with that.
