You can always stop and do a u-turn

If you realize that the choice you made is leading you in the wrong direction in life, then you can choose to stop and do a u-turn. No matter what you have already invested it is not a waste to stop it. It is a waist of your time to continue. We don't always make the right choices in life but it's just an experience in life and you learn as you go. And when you realize that the direction you are going is the wrong choice then your experience in life has taught you to stop and do a u-turn to get back on track. When you choose the path that shows the most traffic you realize it was because others before you went there and did a u-turn and had to go back the way they came in, making the path look more traveled on.
