2nd: Un-wish happiness/ some sort of toggle switch. Happiness needs an opposite to be truly enjoyed.

3rd:That everyone treat every day as if it's "Critical Thinking Day" (aka April Fools). After all, it's the one day no one takes anything at face value.

I would wish for the ability to perfectly mimic any voice I wanted first, and for my other wish, I would wish for a thermos that fills itself with any drink I desire and never runs out.

I would wish for any thought of religion to be banished from the minds of all present and future human beings.

I can't even think of a second one.

To be healthy & to have unlimited funds when needed for anything that I could do without being greedy or selfish.

Great question! As long as that wish for happiness was according to how I define it, I probably wouldn't need the other two; however, my second wish would be for three additionally wishes. I'd wish to end world hunger and poverty, and the third would be the ability to use additional three any time I choose.

With these kinds of wish scenarios the devil is always in the details. "Happiness" could be a drug-induced coma. Each wish must be carefully defined in paragraphs not simple words or sentences. What if the genie misunderstands? I once saw a hysterical bumper sticker advertising a restaurant in Buellton, CA that specializes in pea soup that said, "Imagine whirled peas!" Wishing for "happiness" for oneself in a world full of misery could translate as the IQ of an idiot and the inability to empathize. "Be careful what you wish for" has to be the guiding principle

More wishes and a good stout or porter.

i wouldn't wish for happiness, you'd essentially be asking to have a mind altering amount of dopamine and endorphins being pumped into your head. you'd loose your perspective and your rationality.

other people's happiness

The Tzadik of Minsk once told his student to find and bring back the shirt of the happiest man in the world. After 7 years, the student returned, sans shirt. His master asked if the student had found the happiest man in the world, and the student said "Yes, but he had no shirt..."

Prosperity and endless wonder.

But what if I'm already happy? Do I still have to have that one?
I'd wish that my daughter live a long and happy life.
I'd wish that people would have more self awareness.
