Room Ideas!?

ok so i have a big room but its filled up with tons of stuff. and my room is so mismatched i got it decoreted when i was 6 and it was hello kitty but over a while i changed it and i got a neew cover for my bed(purple and fluffy) and i have lime green sheets under it(i need to keep them there not that old yet). i also have tons of stuffed animals i put them in my closset(its walk in but not thatt big) in abin but its overflowing and i have some on the end of my bed. my room seems to always be messy even after i just clean it its just to much stuff i think.
ok so i want my room to be bright and colorful.
light green, purple, black, annd blue
i was thinking light purple walls and getting painted wood letters like LIVE on one wall LAUGH on the outher and LOVE on the other one and have painted differnt size polka dots on the wall around the words. but idk any other ideas for oganizing and decorations.
im 13 and in 8th grade next year i will be going to high school!
