I am planning on creating decision markets for decisions in my life. For that I want to create a Personal welfare function that then different markets try to estimate conditional on which decision I make. For this to work I need a function that accurately reflects what I value, I am open to suggestions for my function.

So far I would input Income, Happiness (Each week I would estimate my happiness for that week), Career capital, Books (or Book equivalents) read...

I will give bounties for inputs I use in my function.

Any other suggestions for the function are also welcome. Should I just add the different inputs, shoud I use a Cobb Douglas function etc.
