Hope becomes stronger when paired with competence.

Hope on its own is a state; hope plus the ability to actually do things is a position. Competence turns expectation into something you can influence, which is why capable people can afford to be hopeful without it being naive. The skill is what backs the belief.

If your hope feels thin, consider building capability in the relevant area rather than trying to feel more positive. Ability changes the odds and it also changes how the odds feel. The two reinforce each other.
