Im in 7th grade too and i used to wear my makeup the same every day too. so to switch it up a bit... i would match it up to outfits. so say i was wearing a really bold outfit, i would wear very little make up. if that doesn't work for you, here are some tips.
1.use different colored eye shadows, don't be afraid to experiment
2.with eyeliner you could wear only on the bottom, only on the top,corners,and there are so many more combinations...
3.lip stick/gloss, use alot of different colors(pinks,reds,clear,ect.) give the guy you like a surprise every day jk :)
