It'd be great if we could get eight hours of good sleep every day, but the pressures of work or home life can make this lofty goal difficult to achieve. Even so, there are a few tips you can employ to improve your chances of greeting the morning with an energetic smile, as opposed to a depressed moan.
Mark Frost over at HackCollege has posted a few techniques you can use in an effort to become a morning person. His second piece of advice is one I've recently used myself to great effect and if you find yourself with the opportunity to leave your alarm off, I'd recommend trying this out:
Don't set your alarm -- This may not work for everyone ... but when you're setting your bedtime early enough and getting around 8 hours, you'll find yourself waking up without the assistance of an alarm clock or angry roommate. What's even better is that you might develop the habit of waking up at an exact time without the alarm.
Of course, once you do find yourself getting up without an alarm, there's nothing wrong with setting one anyway, just in case. The advantage here is that you'll still get up when you need to (or an hour or so before), but you'll wake up naturally... and feeling like you actually have slept.
