4. Set a sleep schedule
Yes, you’re an adult and should be allowed to stay up as long as you like, but unless you are free to sleep in endlessly that behavior will catch up with your energy levels if it hasn’t already.
You’ve got a good idea how many hours of sleep your body really needs to work at its best. Why not see how it actually makes you feel?
Ideally you’ll choose the same bedtime every night so your body gets into a routine. Get to bed early enough that you consistently get enough rest and before long you’ll be waking up refreshed and energized before your alarm clock.
