Learn and practice to say: No, I am sorry, I don't know, please teach me; When you really don't know, what you are supposed to do; for any reason. No one knows everything but God. Don't waste resources, time by pretending as if you know things, when you really don't. Be humble, learn things as you grow; for we are all learners until we die, and never hesitate to teach others as well, when there is an opportunity. Life is just only once, be blessed and be a blessing to others also.
