Blackhead picking

[spot picking]I have lots of blackheads on my nose. I have tried everything to get rid of them (pore strips, face masks,cleansers, etc) but I still seem to have a lot. I'm usually quite restrained about picking at them as it only makes them worse but when I look in the mirror (particularly in shop changing rooms) I squeeze at all of them and can't stop myself. Please does anyone have any tips on how to restrain yourself.
