Resist the temptation to hit the snooze button; Waking up late will only have a negative effect and make your morning seem rushed and unprepared. Pressing the snooze button repeatedly becomes a habit, not a one-off, so choose a time to get up, set an alarm, and not press the snooze button.
If you find yourself waking up tired, create a nightly routine that will help you go to bed earlier and sleep better. If you go to bed on time, you are more likely to get enough sleep, and when the alarm goes off, you will not be so reluctant to get up.
