Will I go back?

Waited fro someone to cross the bridge and I managed to catch this person just as she half turned and looked back with an anxious look.
So often in life we head in a particular direction and suddenly think, am I going the right way. If that leads to doubt and indecision that is not so good. But if it makes us evaluate what we are doing before moving on or in another direction, that is good. We need momentum - you cannot steer a stationary bicycle.
The person in the image turned and walked on!
