I Propose declaring April as the International Vanity Month (as it's the Month of Aphrodite - Greek Godess of Love and Beauty). Everyone would focus solely on their physical appearance in a personal bid to better represent themselves visually, and thus inspiring self-confidence.

On this month, everyone interested in taking part in this festivity would expoit the gyms, beauty salons, spas, fashion, social scenes, and generally try to be the alpha-male or female in their immediate surroundings.

Local bi-monthly tabloids could be put together, charities, events, ect. could all stem from this month of self-love and complete act of vanity

NB: This is by no means some sort of pretentious atrificial celebration, but rather paying homage to the lovely mythical goddess, and focussing on tangible and intangible self-improvement.
