It's usually much more fun to run along and live life to the fullest than it is to sit back and take stock of your situation, but today it won't seem like such a bad idea to do the latter. In fact, your energy is well-suited for an evaluative approach to what's been going on and what will be going on soon. Reflecting on your own life isn't selfish: it's extremely wise. Besides, if you try to keep things shallow and light today, you won't have much sense of fulfillment.
