If you could ask ONE question?

[Shanto94]

And we would get the answer?

I'd ask "How can I make this world a happier place for everyone in it now and in the future?" Or something along those lines.

I kinda steal this.
Knowledge we would eventually get isn't important, knowledge we can use right now to make the world a better place is very important. And I'd limit it to myself, so I wouldn't need to rely on other people actually caring about this world, because people tend to let you down.

Sadly, I fear the answer would be "Nothing"

What's 2+2?

Just kidding of course.

How can I become rich without ANY effort? :P
