OT- favorite football motivational quotes

So my sons going into his freshman year of highschool. Hes been a starting slot receiver and safety/ corner his whole life. This will be his first time ever not starting. Unless he decides to play JV, the varsity WR coach (me haha) wants him to play varsity and learn under some of our senior players how to work and grind to get where they want to be. (seriously im not the one who asked him to the head coach asked him to move up for depth reasons were a small school) He has a chance to see the field in garbage time in games as typically we have quite a bit of blow outs every season as we've played or won the fla 2A state championship 4 years in a row. But I don't want him to get frustrated and not work hard because hes buried on the bench.

Anyways trying to find some different and unique ways to motivate him and kind of brain wash him into somethings. Ive heard of suggestive thoughts and if you see things enough you kind of with out even knowing your doing so get them stuck in your head. So what id like to do is get some wall clings (like fathead stickers) for his room im looking for the BEST motivational football quote or just motivational quote to kind of get his butt in gear.

Hes not a lazy kid well he wasn't until fortnite came out. He works hard when hes at practice and at weight lifting. Id just like him to do a little more outside of what is required of him so he can set himself apart a little.

Post your your quotes below. hopefully I find something worth using.

heres a couple of examples I was considering....

The difference between
a successful person and others
is not a lack of strength,
not a lack of knowledge,
but rather a lack of will.

A lot of football success
is in the mind.
You must believe
you are the best
and then make sure
that you are.
