Hope researchers often break the concept into two working parts: agency and pathways. Agency is the belief that you personally can make progress toward a goal, while pathways is the ability to imagine more than one route to get there, especially when the first route closes without warning and a new plan is suddenly needed.
The two reinforce each other in practice. Believing in your own capability without any plan tends to produce frustration, while having a detailed plan without believing you can carry it out rarely survives the first setback. Durable hope usually needs both halves working together, not one propping up the other.
This is partly why hope tends to grow through actual practice rather than pep talks. Solving a small problem, then a slightly harder one, builds both a track record of capability and a mental library of alternative routes, so the next obstacle feels less like a dead end and more like a detour.
