Almost always paired with
有 (to have) or
没有 (to lack):
有上进心 = 'has drive',
没有上进心 = 'lacks drive'. Crucially, this is positive ambition - the wish to improve, work hard, climb the ladder - without the slightly cutthroat connotations of English 'ambitious'. Calling someone
有上进心 is a clear compliment.
