Impossible Goal

I am in the process of deciding what my impossible goal could be for 2020. I know that ultimately it won’t matter because its more about who I have to become not the goal itself but I am having trouble picking it because I am wondering what will happen to the other goals on the list.

The can’t go ignored completely. They’re all in different areas of my life and working towards them in some capacity will be important too.

If I prioritize a goal should I still be working towards other goals?
