Are you competitive when it comes to sports? What about your job? Do you approach areas such as parenting, friendship or even your love life with a cutthroat competitive attitude? Dr. Robin says that while it's okay to be passionate about something and really try your best to succeed, you need to be mindful of what you're competing for and why you're competing for it.

Winning someone else's love, approval or admiration should not be your ultimate objective in life, she says. Rather, you should think about what it would really mean to win at living your own best life. "The objective is to decide who it is you are, who it is that you want to be, what it is you value at your core," she says. "And then living your life—each moment that you were gifted with—in accordance with that which you hold in high esteem, with that which has value for you."
