Stay busy. It’s easier to steer something that is in motion than something that is stationary.
My Additional Analogy to this:
Think about riding a jetski. A couple times in my life I’ve been in jet ski accidents and when you let off the gas you can’t steer a jet ski, literally if you are not hitting the throttle of a jetski it just coasts in a straight line. This same idea can be applied to your life, if you are living a sedentary life that is not filled with choices/decisions/actions then you can’t even steer yourself in a good direction.
