How hot is your ambition burning right now? Hmm: that answer sounds close, but try multiplying that by a factor of 10. The stars stoke your drive for success in a big way. This can help you go the extra mile, but if you let it burn unchecked, it could also cause an ego-driven meltdown. The trick to keeping it in check? Checking in with yourself, and making sure you're not so caught up in the race you forget why you're running.
