Breaks should not be a privilege, a sign of laziness, something you are embarassed to ask.
Breaks are important for two reasons.
They help to take distance from what you regularly do. And in doing so, you get the chance to reinforce your dedication and find new ways to approach old problems.
They also promote the idea that no matter who you are, no matter how important the work you are doing, the world is not going to end if you pause.
Take frequent breaks, and take some long ones too throughout the year. Give them all of your attention and dedication. Make them real.
You should be proud of it.
