Wake up when the alarm you set for yourself goes off. Small kept promises add up to trusting yourself.

A promise to yourself is still a promise, and breaking one before the day has even started says something about how much your own word is worth to you. The alarm is a small case, which is exactly why it counts: nobody else is watching, so the only thing at stake is whether you believe yourself. Self-trust is built out of hundreds of boring kept promises.

Set the alarm for a time you will genuinely get up, not an ambitious one. Get up at it for a week, even when the day does not need you yet. If you keep missing it, make the promise smaller rather than louder.
