Ever wanted to ask a billionaire anything? Hedge-fund founder Ray Dalio sat down for a surprise Reddit AMA on May 7 where he answered questions from Reddit users ranging from climate change to his favorite books.

Reddit users (or Redditors) are part of a vast online community with a subreddit for nearly everything. One of the most popular subreddits is "/r/IAmA," where celebrities and authorities in specific fields sit down for the digital equivalent of a radio call-in show (AMA stands for "ask me anything")

Dalio - who founded the world's biggest hedge-fund, Bridgewater Associates, in 1975 - is a self-made billionaire with a net worth of $18.4 billion. He recently launched an app, Principles in Action, based on his 2017 best-seller "Principles," designed to give advice on success in work and in life. Now, Dalio has decided to give out his life advice on the internet to anyone curious enough to ask.

Dalio opened up the question-and-answer session with a post that began: "I'm Ray Dalio - founder of Bridgewater Associates. I'm interested in how reality works and having principles for dealing with it well - especially about life, work, economics and investments. Ask me about these things-or anything."
