When you're working hard all week, how you choose to spend your downtime matters. Here are ways nine successful entrepreneurs and professionals spend their Sundays.

Spend time with family.

When there's little time to spend time with family during the busy work week, Sundays are ideal for making up that time. Bobbi Brown, makeup artist and founder and CCO of Bobbi Brown Cosmetics, has a weekly routine: “We'll have what we call family dinner. About eight to 12 people…I'm always calling last minute begging the restaurants to let us in.”

Catch up on reading.

Carving out time for hobbies allows you to greet Monday refreshed and reinvigorated. Actress Uzo Abuda spends Sundays with a good book: “I'm usually in bed by 10, 10:30 — 11, we're pushing it. I'll start reading. I just finished reading this book, “Ruby,” by Cynthia Bond, which was excellent. “Redefining Realness” is my next book.”

Prep food for the week.

Using Sundays to plan ahead will give you a running start to the week. Caryl M. Stern, president and CEO of the U.S. fund for UNICEF, does just that: “We have a book in our house, and I will write down things for the week: what days I'm going to be away and what's everybody going to eat when I'm away. So Sunday becomes a cooking day. I bake for my kid who's away at college. I will usually bake him muffins. I'm baking for my son for the same reason I'm making eggs for the dog: he knows he's being thought of.”

Do a bit of maintenance.

On Sundays, Carley Roney, cofounder of XO Group (XOXO), does both “virtual” and “real” self-maintenance: “I catch up on the week's weddings on social. I'll take pictures of brides and re-gram them. I'll say congratulations to any brides. I'll search The Knot hashtag on Twitter… at some point in this day, I take the longest shower ever. That's the ‘real me' maintenance. I am invisible.”
