Have you seen people in the airport so overweight, in such poor health, that they struggle to get down the concourse?
Earlier in their life, they did not eat properly or get any exercise. They were content to lounge in a recliner with a case of beer and an unlimited supply of 
Chocolate Oreos. When they could have, or should have, made a change, they chose not to. Or they put it off until it was too late.
There is a strong parallel between those unhealthy people who failed to change their bad habits until it was too late and those who fail to make a career plan. There are clearly bad consequences.
Now is the time to make a plan.
