I think getting up early is the easiest of the twelve constellations. I think it varies from person to person, but to sum up, Leo tends to get up early because their habit is like this. Moreover, Leo needs a long lunch break to recover his strength; She also needs more sleep to supplement all the energy she consumes in dealing with many things all day, but she tries not to show fatigue. At first, Leo will secretly sleep late in the afternoon, which will make her think he is a lazy man. But Leo men, like lions in the jungle, are just lazy in appearance. He yawned, stretched himself listlessly, and then became as active as a cat. Busy repairing this, sewing that, making things completely different, and excitedly suggesting a trip. In a word, I care about everything.
Secondly, I think it's Scorpio, because they believe that everything has two sides, and they like to make progress in unremitting exploration, which is the characteristic of Scorpio. Scorpio's world is full of secrets, which are hard for outsiders to find. It has calm insight and cautious action ability, but it is not easy to be detected. It's hidden deep inside. Scorpio is not sociable, talkative and modest, and is easily underestimated by others. Such people live in their own world, and going to bed early and getting up early is their life rhythm.
Finally, I think it's Taurus, because they work hard and can always stay awake to maintain high-intensity work and study the next day.
