Eat breakfast
To work at your peak performance, your body needs fuel. Rather than just grab a cup of coffee on your way to the office, take a few minutes to eat a meal or drink a smoothie — even if it’s on the go.
Studies have shown that foods high in vitamins B and C allow people to perform better on intelligence tests, while choline, found in egg yolks and nuts, is important for the creation of memory cells. So make a feast of it in the mornings to improve your work performance.
