The truth, straight out.

You will not remember much from school.

School is designed to teach you how to respond and listen to authority figures in the event of an emergency. Like if there's a bomb in a mall or a fire in an office. It can, apparently, take you more than a decade to learn this. These are not the best days of your life. They are still ahead of you. You will fall in love and have your heart broken in many different, new and interesting ways in college or university (if you go) and you will actually learn things, as at this point, people will believe you have a good chance of obeying authority and surviving, in the event of an emergency. If, in your chosen career path, there are award shows that give out more than ten awards in one night or you have to pay someone to actually take the award home to put on your mantlepiece, then those awards are more than likely designed to make young people in their 20's work very late, for free, for other people. Those people will do their best to convince you that they have value. They don't. Only the things you do have real, lasting value, not the things you get for the things you do. You will, at some point, realise that no trophy loves you as much as you love it, that it cannot pay your bills (even if it increases your salary slightly) and that it won't hold your hand tightly as you say your last words on your deathbed. Only people who love you can do that. If you make art to feel better, make sure it eventually makes you feel better. If it doesn't, stop making it. You will love someone differently, as time passes. If you always expect to feel the same kind of love you felt when you first met someone, you will always be looking for new people to love. Love doesn't fade. It just changes as it grows. It would be boring if it didn't. There is no truly "right" way of writing, painting, being or thinking, only things which have happened before. People who tell you differently are assholes, petrified of change, who should be violently ignored. No philosophy, mantra or piece of advice will hold true for every conceivable situation. "The early bird catches the worm" does not apply to minefields. Perfection only exists in poetry and movies, everyone fights occasionally and no sane person is ever completely sure of anything. Nothing is wrong with any of this. Wisdom does not come from age, wisdom comes from doing things. Be very, very careful of people who call themselves wise, artists, poets or gurus. If you eat well, exercise often and drink enough water, you have a good chance of living a long and happy life. The only time you can really be happy, is right now. There is no other moment that exists that is more important than this one. Do not sacrifice this moment in the hopes of a better one. It is easy to remember all these things when they are being said, it is much harder to remember them when you are stuck in traffic or lying in bed worrying about the next day. If you want to move people, simply tell them the truth. Today, it is rarer than it's ever been.

(People will write things like this on posters (some of the words will be bigger than others) or speak them softly over music as art (pause for effect). The reason this happens is because as a society, we need to self-medicate against apathy and the slow, gradual death that can happen to anyone, should they confuse life with actually living.)
