How is it that people can commit to things? Why do they believe they will succeed?

Why and how can they believe in themselves? Where does that faith come from
EDIT: Or perhaps i should say where does your faith in yourself come from?

@YesNoMaybeSo that seems to be the most common answer I see. That peoples faith in themselves come from their achievements, and in some of those answers they say that through smaller achievements their confidence gradually grows over time. But regardless of that it makes me wonder, what if someone has no achievements or if the individual is incapable of recognizing their achievements as achievements and just sees them as rudimentary?
