My first acid trip was on a Wednesday night at Burning Man, and it was beautiful. That said, my tripmates and I prepared carefully for our voyage. Below are the things we did to make it enjoyable. Take this information as you will.
Do it in a group of about four people who all like and respect each other. (No more than five or you will lose a few wanderers.) At least one of you should have prior acid experience and act as a trip guide-- the leader who compels everyone to follow him/her to the next adventure. It would help if your leader is dressed in something interesting to look at, like EL wire at night, so they'll be easier to track. It may also be preferable if your leader is hallucinogen-sober, in case you run into any difficulty dealing with regular people or cops.
For your journey, bring water that's easy to drink and food that's easy to eat. (You may not like Clif bars, but they get the job done in a pinch.) Dress in clothes that are easy to undo in a porta potty at night. You may be in a completely altered state for what feels like forever. Plan ahead to stay physically comfortable.
Have a blinking/glowing thing on you, even if you plan on tripping in the daytime. Your trip may last well into the night, and you don't want to be in the deep playa without any lights-- art cars will not see you.
Have your name (playa or real) and the name and location of your camp written somewhere accessible in case you're lost and non-verbal.
Make sure you're in a calm, relatively healthy state of mind when you begin. If you're trying to be chill but underneath that calm exterior is a tumultuous mess of thoughts and emotions, the acid will find it soon enough.
If you're unsure about your dosage, don't take more in a few hours if you haven't started feeling funny yet. When it comes to recreational drugs, not being on enough is generally better than being on too much. I've had a trip or two where I re-dosed in hour three and then
began to feel the first dose, and it gets intense. Don't do this your first time.
If you're overwhelmed by everything, I suggest walking to the temple with someone you trust. (The trash fence is too far if someone needs to actually get you help.) Things are quieter there, and you can remind yourself that not all is lost, and this thrill ride will be over in a bit.
If you're really
overwhelmed by everything, a small amount of an anxiolytic like Ativan has helped me calm down before. (I've also successfully used a little ecstasy to counteract a bout of paranoia, but if you've never taken it before, it's not a great idea.) As with the rest of this information, your mileage will vary.
One of the best things about tripping on the playa is that you can act like a little kid without anyone looking at you funny. And you are! You're experiencing the world anew. Play with your friends, get distracted by shiny things, and remind each other that cars are real.
As for the original question-- think about your life and where you want it to lead you. Think about where you've been and what you want in your day-to-day life to be satisfied. Think about the world and yourself and what you can do to change them both for the better. And look forward to how easy doing normal things will be once your trip is over and you can function like a regular human being.
Good luck. Have fun. I hope you understand yourself better afterward.
