modest

謙虚(けんきょ)	This is a word you use about others. “She’s got a very modest attitude.”

謙遜(けんそん)	To downplay your own skills in front of others. You don’t ever say “I 謙遜-ed.” or “She’s really 謙遜-ish.” Normally it’s only used like:“Please don’t kenson. We both know you’re rad.” or “He declined the offer out of modesty.”
