"Goaltending is what you do, but not who you are," Stevenson said. "You must be in the moment. When you're at the rink, be at the rink. When with family, be with the family. Be 100 percent where you are at that moment."
Hart has counted on Stevenson for advice many times throughout his career.
"I always call him the night before a game and he'll settle me down," Hart said. "Sometimes we'll just talk because we're good friends, and other nights when something is on my mind or bothering me, I can talk to him. He'll provide opinions on things and teach me what I need to do to fix it.
"Sometimes when the coaches aren't happy with your play or if they say something that might stick in your head, [Stevenson] will set me straight. It usually has nothing to do with your game or with you. In the end, you just have to go out there and do your job, and that really helps me focus."
As a goaltender, getting over the mental hurdle is more than half the battle, and Hart seems to have the right approach.
"To be successful in this business you have to have a lot of fun, because that's when you're playing your best," Hart said. "When you're not thinking and just playing, that's when good things happen."
A lot of good has happened to Hart this season, his second in the Western Hockey League.
The 6-foot, 177-pound left-handed catching goalie led the league in wins (35) and finished second in games played (63), goals-against average (2.14) and minutes played (3,693) in the regular season. He was tied for third in shutouts (six) and was sixth in save percentage (.918).
Hart is No. 1 on NHL Central Scouting's midterm list of the top North American goaltenders eligible for the 2016 NHL Draft. In his only WHL playoff game so far, he made 28 saves in a 4-2 win to eliminate Portland in Game 4 of a first-round series March 30. Everett will play at Seattle in a best-of-7 second round series that begins Friday.
"He's very poised, patient and calm in the net," Central Scouting's Al Jensen said. "He doesn't get rattled, has an excellent butterfly and seals the ice well with his pads. He can keep his body upright to protect the upper corners, has a good glove hand and good rebound control."
He's glad to be recognized so highly by Central Scouting, but knows there's more work to be done.
"It's just a ranking, the draft is still months away and we have a lot of games remaining," Hart said. "Hopefully, we'll get a chance to raise another banner in Everett this year after raising [a division title] for the first time in nine years in 2014-15."
