Sticking a toe in the water is a wise way to get familiar with a new concept, person or place: just make sure you don't dive in head first as soon as the temperature feels right. A lot is at stake now, and you need to make sure you know how deep this water goes: and if there are any sharks swimming around! Be thorough when you evaluate things today, from checking the temperature of your coffee to assessing a coworker to evaluating a new car you have your eye on.
