Happiness Ratio

I quote from The Straits Times (24 Jan 06) which reported a London News –
“ A British university researcher claims 23 Jan the gloomiest day of this year….The formula looks like this :
W + (D-d) x TQM x NA
Where :
W = weather
D = debt
d = monthly salary
T = time since Christmas or since failure to quit a bad habit or low motivational leval
NA = need to take action

This is true especially for in cold places now eg. Britain and America.
23 Jun on the other hand is the happiest day of the year due to the weather and more emphasis on nature with flowers and trees in full bloom.”

My personal happy-day ratio (the opposite of the above formula) is as follows :

If offday or public holiday, HPratio = 1, else

HPratio = (A x H x [(d-D)/30] x G) / (O+W)

Where :
A = achievements in the form of personal motivation or job satisfaction
H = heartwarming moments
G = personal & loved ones’ good health
d = monthly salary
D = debt
O = occasions of disputes at work and family
W = weather

Happiness is fleeting and short-lived. It is something everyone yearns to have, yet difficult to find at times.
On the hand, anyone can have it if one disregards everything sad around you (eg. debts, poor relationships, low self-esteem etc) but wouldn’t it be self-deception at the expense of happiness?

Life is too short to be unhappy but is it too short for self-deception?
