The only way to maintain a good relationship with your graduate school advisor is to work hard, submit your work on time, see him at least once a week, and make it clear to him that you are willing to learn from him. Be a student, don't try to be his teacher. Don't take his constructive criticims as personal. Ask him to challenge you..engage in serious debates woth him. State whatt you feel politely and firmly without sounding like a prof. Know that you don't know much and your advisor is tehre to help you learn more. You know your advisor likes you when he starts reccomending or lending you books/articles from his personal collection. Read, write and speak.. that's all. You don't have to do anything else besides those. That's from my experience.. and I didn't attend graduate school in America.
