Once you taste life at the top, you'll never want to settle for anything less.
In Andy Murray's case, Monday's breakthrough at the U.S. Open will have him aiming for the top, and nothing less for the rest of his career.
Murray survived a five-set thriller against Novak Djokovic in the men's final at Flushing Meadows on Monday night to win his first career Grand Slam championship.
Now that the heartache and heartbreak of losing four Slam finals is finally behind him, the 25-year-old Scotsman can focus on winning more, and not just one.
It's not as if Murray is new to the tennis spotlight, and the world is now scrambling to figure out who he is. He has been a force and a favorite throughout the past few years at each and every Grand Slam tournament.
Just last July he led Roger Federer by a set in the Wimbledon final, before losing three straight to Fed to lose his fourth straight Slam final.
And even before Monday in Queens, Murray had been a finalist at the U.S. Open. He made his first Slam final appearance there in 2008, losing to Federer in straight sets.
Murray has even found success at the year's first Grand Slam, the Australian Open. He made two straight finals in Down Under in 2010 and 2011, losing both in straight sets.
How many Grand Slams will Andy Murray have won when he retires?
All Murray needed was a breakthrough. Something to help him believe in himself and to give him the confidence to know he can do it again.
With the help of Ivan Lendl as his new coach this year, Murray has finally joined the sport's elite and becomes the only other player besides Juan Martin del Potro not named Roger Federer, Rafael Nadal or Novak Djokovic to win a Grand Slam in nearly eight years.
With Nadal currently dealing with serious knee issues, and Federer attempting to remain atop the sport at age 31, Murray is in the driver's seat to win more majors.
He knows he can win, and he knows he can do it against the world's best. As a tennis fan, I'm incredibly excited to see what the future holds for Murray, and a potential developing rivalry between him and Djokovic.
Their five-hour match on Monday night was no doubt a preview of what's to come in the next few years. Along the way though, Murray finally cemented himself as a Grand Slam champion and let the world know that there are more to come.
