Overdoing it is great
. . . in terms of preparation. Being comfortable is not a sin. Prepare for the worst so that you can enjoy yourself properly, and so that no one else has to take care of you at an event where Radical Self-Reliance is a founding principle.
If you have a tendency to overdo absolutely everything: remember to drink electrolytes, not just water. Bring a backpack or messenger bag to tote your beverages and sunscreen and hat and goggles, because a person who Overdoes It will no doubt step out for "twenty minutes" and be gone for 12 hours. Remember to eat, and to get some protein at every meal. It's really easy to dehydrate, and then not be able
to eat (or keep anything down).
