Great tips already. Set and setting are the most important. I like to meditate a little beforehand and think about what a positive time I’m going to have and what great experience it will be. Also, spend as little time on your phone as possible. Even put your phone somewhere you won’t be as tempted to use it. Be in the moment with your friend, interact with the world around you. Sometimes you might get the feeling you need to text or call somebody to tell them something you think is important… Wait until you’re done tripping and see if you still want to. Take this time for yourself and the people you’re physically near. There’s plenty of time for the rest of the world later.
