The lot assigned to every man is suited to him, and suits him to itself.

Circumstances and people shape each other over time. Whatever you were handed, the work, the family, the constraints, has been forming your habits for years, and you have adapted yourself to it in return. That is a description of how lives and conditions grow together, not a claim that anyone earned what they got.

Instead of asking whether your situation is fair, which often has no useful answer, ask what it has made you good at. Then check whether you are using that anywhere on purpose. People often carry a capability built by a hard stretch and never apply it elsewhere.
