Is your profile filled with old buzzwords? They make you sound out of touch. So wipe them out.
According to LinkedIn they are: creative, organizational, effective, extensive experience, track record, motivated, innovative, problem solving, communication skills, dynamic.
Other buzzwords to avoid include: results oriented, team player, self-starter, multitasking.
