You will not find bullocks, nor will donkeys carry your burden.

This couplet gently reminds us not to expect too much from limited resources. It advises against burdening those who are not equipped for heavy tasks. Just as you wouldn't expect a donkey to carry the load meant for an ox, it encourages us to be realistic about what others, or even ourselves, can handle. It's a call to understand individual capacities and not overload them, suggesting that sometimes, ideal support isn't available, and we shouldn't force a mismatch. It teaches us wisdom in assigning tasks and managing our expectations thoughtfully.
