Sorting

Today the boys wanted me to "play cars" with them. I'm not very good at that, but I managed to convince them that it would be fun! to sort the cars into colors...
       red...  
                        blue... 
                                          green.... 
                                                               yellow...

In my mind these days I'm doing my own sorting. What's important and what's not? Is it enough to "just" be a mom? Where else should I invest myself? And how much of that sort of investing can I handle? Where do I want to be 5, 10, 20 years from now? How do I prioritize all the little things -and big things- that I encounter in my days? Which of those things will really matter later, in the grand scheme? Sorting, sorting...
