It's also messy English - it really needed some revision before posting, but oh well. Here are the corrected expressions, with explanations: "I am down-to-earth" = I am a practical and sensible person. "career-oriented" = my main focus in life is to work successfully. (Note the spelling of "career". A carrier is something that carries things, like a logistics or telephone company, or a hotel bellboy.) "optimistic" = positive-thinking "and have a good sense of humour" = I'm fun company, and not always serious.
