Do you take your car to the mechanic for regular tune-ups? Or do you wait until something breaks before you get your car fixed? Do you visit your doctor for routine checkups? Or does it a take a serious illness to get you thinking about your health?

Dr. Robin says the time to care and the time to act is right now—whether it's your car, your health or your relationships. Don't wait for something to go wrong before you begin to do the right thing.

"If you expect a return on your investment, that means you've got to pay attention and you've got to do it now," Dr. Robin says.
