Mirrors
I think of one good quality that I am proud of when I look in the mirror - whether its my eyes or make up or even my nail polish (it can be the smallest thing). Then the next day I think of another good quality in addition to the previous one. Eventually the good qualities seem to outnumber the negative qualities about yourself leaving you with more self confidence. Also, if you find at least one good quality in yourself everyday you act more poised than always putting yourself down with harsh thoughts.
