How to keep my inspiration level up for next year and half of basketball?

so, im a junior right now. i've played since i've been in 2nd grade. i used to be so much better and love it much more and even be like the total star of my rec team when i was little, but then this thing happened o me in 6th grade, and i ended up in a coma for a few weeks then a bunch of hospital time to come out from that ect. it messed up everything. the pills that they had me on at first made me gain tons of weight. im now like 170, and that's after me working on it for a while. i was like way up at 190. im hoping to work like 10x harder and ose some more for senior year but any way. because this whole thing brought up my weight and down my speed and ability, my basketball career went totally down the drain. so, i still made my hs team, but im definitely not that great of a player. i even thought of giving up at the beginning of this year because i didn't think was good enough. but i managed to get past that, but i still wasn't having that much fun. ...now, im not that much of a miley cyrus fan, but last night, i heard this song, i'll always remember you by her, and it just put this vision in my mind of my senior night next year, and i took a minute and realized that its come down to this, and sadly i only have one and a half years left of basketball to play in my life. it sorta made me cry. but, now im thinking, from now till the end, i just gotta give it my all to have the best rest of my career possible. how can i keep this in my mind the whole time im on the court? because i don't want something bad to happen and get me down. i want to be able to give it my best 100% of the time because ....i realized im almost done. ....is there something good i could write on my shoes or something? or any other sort of ideas?
