Continuing my reply:
I wonder how you decide which goals you’ll actually pursue in your life. I think living your life can be one big project and you can choose which goals you want to pursue for that project.
Im thinking you could still pursue a goal even if it has an error that makes it fail. You can still pursue even if you evaluated that a plan/solution will fail at a goal. The question you would have tho is why it failed and why pursue it?
