Goals versus purpose

Hi Brooke, I’m hoping you can give me some advice on when to make something a goal vs a purpose. At this stage in my life with young kids at home I know that my most important job is to care for my kids and support them to flourish. There is no doubt for me that this comes first. I could treat this as my purpose (for now) or a goal within a broader purpose like caring for others. Or even “my purpose is to commit wholeheartedly to reaching my goals”. For purpose do you recommend broad and over-arching or nicheing in? Do you have any pointers on what makes a good goal vs a good purpose?
