Making mistakes helps personal growth
But only to a certain extent. Do listen to your RM's suggestion to not smoke in your room; don't ignore your professor's advice to study for weekly quizzes. But chances are, after going to a few orientations and attending a few socials, you'll get a lot of tips from upperclassmen that might not always be worth taking to heart on things like how to make friends, what to prioritize in your life and when to study. Ultimately these things are individual opinions, and holding fastidiously to these pointers could do more harm than good.
When you heed every warning you hear, you adopt assumptions about the world around you, and nothing is more likely to stunt your personal growth than assumptions. Sure, you may be more likely to trip and stumble, but you're also more likely to expand your possibilities to their full potential. As famed director Billy Wilder put it, "Trust your own instincts. Your mistakes might as well be your own, instead of someone else's."
In the end, college is an experience, an exploration best discovered outside the velvet ropes and traffic cones. College is best when discovered by you.
