• 14．Ways to Finally Become a Morning PersonCalculate your perfect bedtime
     The easiest way to wake up earlier in the morning is to get enough sleep.（1）

  ：For a week，remember the number of hours you sleep，including weekends.Divide that number by seven to calculate your nightly need.Think about a time you've been on vacation or of a night you felt particularly rested-how much sleep did you get？Once you have that number，calculate backwards from the time you want to get up and plan to go to bed at that new hour.
  Find out your stay awake things
     Nighttime can go away fast，especially when you have a lot to accomplish.To be successful in having an earlier bedtime，you may need to set an alarm.And contrary to popular advice，you don't have to turn off the light right before bed.（2）

  ，but reading a thriller may not be the best idea.
  Create a morning to do list
     Another good habit is to think about what you want to accomplish in the morning.Having a morning goal is the best motivation（动力）.（3）

  .This way you'll feel like you're on a task when you wake up，you'll get closer to your morning goal and you'll have a clear schedule to follow. （4）
