What’s that sparkling in the air today? It’s the spirit of competition. But if you’re in a risk-taking mood, calculate your bets appropriately. Whether you’re daring yourself to give an outlandish pitch at work or just to tackle all of your domestic chores in one day, make sure you’re not overtaxing your system. Courage is required to accomplish all great deeds, but not at the expense of your limits. Knowing when to call it quits is its own type of victory.
