Practice sleeping habits that will improve your focus and productivity.
Even sleeping an extra 15 to 30 minutes a night can help you feel rejuvenated and ready to tackle the world. When you do not get enough sleep, it leads to a cascade of negative events: your productivity at work will be affected, you may have to skip regular exercise or spending time with your friends and family, etc.
Furthermore, snoozing your alarm and catching an extra 15 minutes of sleep in the morning does not actually count toward your total amount of deep restorative sleep. Forcing yourself to get up as soon as your alarm goes off will refresh you much more than snoozing your alarm.
