Has to be happiness.
I spend most of my free time, money and effort in a constant quest to continue my happiness. Although money would help, it's not always necessary.
I've found contentment in isolated (less travelled, not neccesarily distant) areas of Ontario just from the wonders of nature and I'd probably be quite content to live on a beach in Mexico living off of coconuts and complimentary nachos discussing politics with Rico the local dog.
Providing my camera comes with, of course ...
It is sad, but money will get you the rest. With money, most people are happy (and those who aren't likely wouldn't be anyway) as they can do what they want to do. With money, it is easier to find love. You can make yourself better looking, afford to go to places to meet people and it makes you more attractive to others. With money, you can afford to be healthy. Better food costs more than crap, so it is easier to eat better, you can afford a gym membership, etc. Money may not buy you sanity, but people will tolerate your insanity, in fact, you will cease to be insane and will become eccentric. With money, friends may be easier to find, though not ncessarily. And lastly, with money, you can buy all the pizza you want!
Sorry to be crass about it, but it is true. Money opens a lot of doors, simple as that. I wish it weren't so, but I am a realist, not an indealist.
I picked happiness because it comes after some of these things. A lot of the choices go hand in hand. Like pizza = happiness. Love = happiness. Good health = happiness and etc... Money though is not up there in my list. it's good for the bills and my film but I don't need it to be happy. The best things in life are free.
