According to countless research studies, people who go to bed and rise early are better students. Harvard biologist Christoph Randler found that early sleep/risers are more proactive and are more likely to anticipate problems and minimize them efficiently, which leads to being more successful in the business.
Other benefits of going to bed and rising early — backed by research — include:

Being a better planner
Being holistically healthier as individuals
Getting better sleep
More optimistic, satisfied, and conscientious

Waking up early allows you to proactively and consciously design your day. You can start with a morning routine that sets the tone for your whole day. You show self-respect by putting yourself first. In your morning routine, you can pray/meditate, exercise, listen to or read inspiring content, and write in your journal. This routine will give you a much stronger buzz than a cup of coffee.
