On Saturday, when Swansea visit Goodison Park, it will be exactly 10 years since the midfielder made his Blues debut.
Osman told evertontv: "I feel like I'm 21. I feel young and good and hopefully I'm going to continue to feel like that and continue to play in the first-team.
"I'm delighted to have achieved 10 years. It's something that you want to do - you grow up wanting to play for Everton. Not only have I done that now, I've done it for a decade. I'm thrilled."
