Six seconds can change a singer’s life. Don’t believe us? Just ask Shawn Mendes.

Back in the summer of 2013, the Canadian native had an idea to perform a cover of Justin Bieber’s “As Long As You Love Me.” But instead of uploading the rendition on YouTube, he decided to share it on Vine.

“I was sitting in my bedroom and my sister came in and I said, ‘Hey, can you record this?'” he recalled to Billboard . After singing six seconds of the chorus, the video “blew up overnight” and helped turn Shawn’s musical dreams into a reality.

Island Records signed him in May 2014. His first single “Life of the Party” sold almost 150,000 copies in its first week without any radio promotion. And his debut album Handwritten landed on the top of the Billboard 200.

As Shawn celebrates the release of his brand-new self-titled album today, it’s impossible not to recognize and applaud a young man who defied expectations, wowed critics and impressed fans under the spotlight. And yes, he did it all with little to no drama.

So how did he go from a Vine star to a man headlining his third global concert tour before turning 21? One of the many reasons is the famous friends he surrounds himself with.

One Grammy winner in particular is Taylor SwBift who asked Shawn to open for her star-studded 1989 World Tour in 2015.

Before his first show with the “Shake It Off” singer, Shawn couldn’t help but express his excitement at hitting the road with someone who he’s admired for so long.

“She’s the biggest of the big and she’s just amazing,” he told James News when appearing at the 2015 Radio Disney Music Awards.

“She’s one of the best people I’ve ever met so I can’t wait to go on tour with her.”

And while the chance to perform in front of countless sold-out arenas is a gift in itself, Shawn also remembers the priceless advice he received from the veteran performer.

“She told me not to be afraid to go out on stage because everyone in the stadium came to have fun,” he recalled to VMAN magazine . “This is not a judging contest, this is a concert.”

Just last weekend, Taylor invited Shawn on stage as the reputation stadium tour traveled to the Rose Bowl in Pasadena. The song they performed in front of 80,000 people? Shawn’s own hit “There’s Nothing Holdin’ Me Back.”

More recently, Shawn has developed a strong friendship with John Mayer and Khalid who are both featured on his new album out today. In addition to creating new sounds together, the artists have been able to inspire each other and drop some wisdom only a certain few would understand
