Best way to work efficiently

At the beginning , it was hard for me to focus on my work . But i succeeded with time. I'm sleeping enough ( i wasn't before ), doing sport and eat healthy food to get an ealthy lifestyle so i'm not tired , not hungry and i'm not full of energy while doing my work. I usually listen to calm music or ASMR that helps me focusing on my work. Have a great day , i hope this will help you !
