Here are some tips to achieve "Hygge"

#Mood

The country with the most number of per capita candle-lighting attempts in Europe.
The country whose half the population light up candles almost every single day during the fall and winter periods.
The country where a party-pooper is called 'lyseslukker', which literally means someone who blows out a candle lighting up a candle, a beginning of "Hygge".

#Sweet

A cup of tea with honey
Cake with sugar powder spray on it
Chocolate with a warm cup of coffee
...
The flavor of "Hygge" is something familiar sweet and comforting

#Harmony

A strong correlation between interpersonal relationship and happiness!
Amicable interpersonal relationships are the most important variable to bring happiness... family, love, friends and neighbors...
Spending time with someone you are comfortable with and close to is a key element of "Hygge".
