Take everything you believe in, think about your life, or any idea you have before eating mushies and throw that shit out the window. Cause you're gonna think and believe in the craziest shit now. Atleast thats what happened to me. Make sure you have fun though, and I agree with everyone else, get outside and adventure. If there is a person who is sketching you out, especially before youre tripping and they know you are, get the fuck out of there because it could send you into a bad trip. When I did shrooms for the first time, before I was tripping, this kid tried to scare me by telling me there were snakes everywhere. I got in my car and drove home. I thought it was better alone than if it had been with those dicks. Yet, driving on shrooms is not something I ever recommend anyone doing. If you do end up inside though, i suggest trying to write down all the thoughts you are having or drawing. (I have a friend that keeps a booming journal he writes in every time he trips) They will be cool things to look back at after your trip and who knows, maybe a masterpiece will come out of it haha. Just remember, have fun and enjoy the ride!
