How do you be confident if you dont understand something?

Question

Like if you dont know how to do something or how something works, how do you still be confident

Answer 1

Just do it. Hardest part is the plunge, everything else comes easy. And don't be afraid to ask questions.

Answer 2

REMEMBER: IT IS BETTER TO BE THOUGHT OF AS IGNORANT THAN TO OPEN YOUR MOUTH AND PROVE IT!

Moral of the story: Read, listen, observe and learn. Then when you KNOW the subject, be confident about expressing yourself!
If someone disagrees, that is their opinion and they are entitled to it, just as you are to your opinion!
