Here are some quotes about asking for help:

"Don't be afraid to ask questions. Don't be afraid to ask for help when you need it. I do that every day. Asking for help isn't a sign of weakness, it's a sign of strength. It shows you have the courage to admit when you don't know something, and to learn something new." - Barack Obama

"Asking for help is never a sign of weakness. It's one of the bravest things you can do. And it can save your life." - Anonymous

"However, if you find you can’t help yourself, there’s no shame in asking others for help. Sometimes asking for help is just as heroic as giving it." - Rick Riordan
