Legendary Ukrainian boxer Wladimir Klitschko spoke about one very important life rule that helps him to constantly be in tonus and ready for any challenges.
"Changes happen faster than we expect, and more often than we want it. Well, if you have an understanding of this and the opportunity to prepare for them in advance. But in any case, one day you realize that you can no longer do what you have been doing for a sufficient period of time in your life. Time is the most valuable and most important currency. And that's why you need to dispose of it very correctly," Klitschko said.
