There is also a saying that "The early bird may catch the worms, but the cool worm stays in bed".
It isn't really when you get up that matters, but what you do with your time whilst you are awake. Some of my most creative work has been done by working through the night.
I agree with this.
Some people prefer to work on evening because they can focus and can think thoroughly while others prefer to do it early in the morning.
So I think it depends. What matters is you're working hard and dedicated to become successful.
