You cannot put the same shoe on every foot.

You have to be careful what you do because the shoe may be on the other foot someday.

Reshape one's foot to try to fit into a new shoe.

Shoe strangles the foot. But it advances. (La chaussure étrangle le pied. - Mais elle fait avancer)

Now the shoe is on the other foot, I am asking the questions.

Do not turn back when you are just at the goal.
