#1 Put on a sparkly party dress
#2 Find some sparklers and champagne
#3 Drink champagne and dance the night away
#4 Crash out with your loved one
#5 Steal a steamy kiss from aforementioned loved one.
Or do what I'm doing; get in your pajamas, make yourself some mimosas, order in food, watch When Harry Met Sally, and kiss your handsome fiancé when the clock strikes 12.
Happy New Year!
