Some are night owls. It's okay if they are creative and ingenious in their work during the quiet night hours. It’s just important that you know how you work and who you are as a person.

A simple rule to follow is: if you do your most creative work at night, work at night. If it’s in the morning , work in the morning. No matter when you choose to work, it would be tough at the beginning. It will test your willpower. Be prepared.
