Done Quote by Brian Tracy
“Do one thing at a time. Start the day with a list of things you have to do, and do the most important things first. Even if you don't get the list done, you've gotten the most important things done. So many people spend so much time on things that aren't important.”
![“I've used the Phoenix Centrifuge to replicate what the body's going to go through on the flight up. I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
