Q: If you don't have the ball's packaging, check the ball itself; the intended size is often printed near the air valve or on the ball's "equator." Use a yardstick or tape measure and make sure this distance is exact. The box you use should measure at least as high as your fitness ball. If it passes through without brushing either, it's underinflated. When correctly inflated, the edges of the ball should just graze the box and the wall. If you don't know the ball's intended diameter but need to know its actual size, place the ball against the wall. Position the box so that it just touches the opposite side of the ball. Then remove the ball, and measure from the box to the wall to calculate the ball's diameter. Alternatively, you can use your ball’s height to determine whether it’s inflated correctly. Use painter’s tape and make a mark on your wall at the same height as the fitness ball’s diameter. Then, inflate your fitness ball until it’s level with this mark. The diameter of your fitness ball is the same as its height.
A: Check the ball's packaging for the ball's intended diameter. Place a large box away from the wall at a distance equaling the ball’s diameter. Roll the ball between the box and the wall. Measure the height of your fitness ball against a wall.

Q: Part of being sweet means that you are thoughtful towards other people. You can achieve this by showing interest in other people's lives, or by doing nice things for them. For example:  Instead of talking about yourself, you can ask your friend about his day. This will show your friend that you are interested in his well-being. If your friend reveals that he is having a bad day, you can show how sweet you are by buying him some ice cream. It is your friend's birthday. Unfortunately, it falls right during Finals week and ends up being forgotten by everyone else as they scramble to complete assignments and catch up on last-minute studying. You can surprise your friend by bringing her a cupcake or a balloon to school. Part of being sweet is also being caring, which can be achieved through showing concern for other people. For example, if you notice someone looking upset, ask him or her what is wrong and if there is something you can do to help. This will show him or her that you care, even if he or she does not want any help. Part of being sweet means that you are polite and have good manners, even towards those you dislike. This means that you say things like "please," and "thank you," and "excuse me" or "pardon me." For example:  If someone compliments you, smile and say "thank you!" If you are eating in a cafeteria, and the salt shaker is too far away, do not reach across someone's face to grab it. Instead, ask: "Could you pass the salt, please?" If you are in a hurry and need to get through a crowd quickly, try not to shove your way through. Instead, say "pardon me" or excuse me" and try to weave your way past people instead. This does not mean that you have to donate all your clothes to charity and give in to everyone's demands. You want to be generous to a certain extent, but not so much that people begin to take advantage of you. For example:  Your friend forgot to bring her lunch to school, and she has no money to buy something from the cafeteria. You can offer part of your lunch to your friend, or lend her some money so that she can buy something to eat from the cafeteria. If the boy sitting next to you forgot to bring a pen or pencil to class, offer him one of yours. If you suspect someone taking advantage of your generosity, it is okay to confront him or her about it, so long as you do it in a gentle, non-accusatory manner. For example, if your friend asks you for lunch money every day, you can try saying: "Alright, I will help you one last time, but I really cannot afford helping you every day. What about bringing your own lunch from home tomorrow?" Not only will complimenting others help boost their self-esteem and make them feel better, but it will also make you appear kind and sweet. For example:  If your friend got a new haircut, tell her how cute it looks. She may be feeling self-conscious or uncertain about the change. Your compliment might just give her that much-needed boost of confidence. The boy sitting next to you in class draws almost the time. Instead of just telling him that he draws really well, mention a particular detail, such as hair or eyes. You could say something like: "Wow, you are really good at drawing! I really like how you did the eyes!" Do not be over-generous with the compliments however; you might come off as creepy, annoying, or fake. You want your compliments to be genuine (or at least appear that way). Sweet people are the ones who are the first to offer help, even if it is not wanted. There are many ways you can help others, and some of those ways are small and almost effortless, such as opening doors. You can show your sweetness by offering help in many situations, such as:  A girl has just dropped all of her books. Instead of walking past or laughing at (which a sweet person would never do), go over to her and help her pick the books up. A boy is helping set up for the school charity and has taken on more than he can can handle—literally. He is carrying way too much, and all of the boxes are falling out of his arms. Go over to him and offer to help him carry some of the boxes. An elderly man in a wheelchair is about to leave a cafe, but the door is closed. You can show just how sweet you are by holding the door open for him. Don't forget to smile, and say "You're welcome!" if he thanks you. Sweetness is associated with softness and gentleness, so try to use a softer voice when speaking. This does not mean you must talk at a whisper or use a high-pitched voice. Just soften your voice to a low and gentle level. This will help you sound kinder.
