just breathe, it´s gonna be ok
learn your limits
know what you want
try as much as you can, go for clubs, try out new classes
work on yourself, no friend of yours is gonna live your life instead of you
know your priorities
have fun
don´t get into dumb shit
don´t stress too much over things you can´t change
do your best even though it´s not everyone´s best
be proud of yourself no matter what
high school is not the end or the start of the world
everyone makes mistakes
learn to ask for help
talk to teachers if you have a problem
don´t share things you are not 100% comfy about
some people won´t be your friends forever and it´s ok
teachers are not your enemies
stand up for yourself and for others
be polite to everyone, including janitors
do your homework
find your interests and try to make them your goals
make good work your aesthetic
don´t be afraid to be a bit silly and have fun
get to know people you´d normally never talk to
