Present participle of career: moving at high speed or advancing quickly through professional life; rushing forward rapidly.
From Middle French carrière (race course) + -ing (present participle). The term evolved from literal horse racing to metaphorical rapid movement in any context.
Famous author Charles Dickens used 'careering' over 50 times to describe wild, chaotic motion—the word became so associated with Victorian literature that it almost feels like a ghost of 19th-century prose!
