The former Yeovil Town loanee says that manager Roberto Martinez has informed him that his Toffees future hinges on his hunger to fight for a place in the squad this summer.
"Roberto told me that pre-season was my chance to shine and he's said to me that if I am where he thinks I am - from what he's seen of me this season - then I'm going to be involved," he told the club's official website.
"And if I'm not, we'll see at the end of pre-season what we're going to do. It's a big summer for me, it's up to me.
"Seeing Seamus progress is brilliant for me because he's such a hard worker and it's a reward for how he lives. He's very good to me, he says, 'If I can do it, you can do it', so we'll see what happens."
The Republic of Ireland defender made 37 appearances for Yeovil last term.
