'Tis a long lane that has no turning.

Difficult or unchanging circumstances need not continue forever. Even a seemingly endless stretch of hardship may eventually change direction, creating an opening for improvement or relief.

The saying counsels patience and hope rather than predicting a particular outcome or when change will come. It frames reversals as part of life, reminding someone not to treat the present condition as permanently fixed.
