Hey Heidi!
to the WW Flex area ^_^
You're given 20 points a day, and then there's the 35 weekly points, too.
The 20 Points is your daily minimum. They're you're base points. And you should strive to eat each & every last one of them. (It shouldn't be that difficult!)
The 35 weekly points are yours to do with what you want. You may add a few points to each day. You may eat them if you have a special dinner one night a week. You may also choose to not eat any of them. It's up to you! (I usually don't recommend not eating them, though...)
