Take a note book and make time each day to write down how the day panned out, who you met, what you saw (animals, birds, trees, locals, dramas), how you feel and what you eat. You'll review this with your photos when you get home and the safari will stay that much sharper in your mind.
Make sure you understand all of the functions on your camera so that nobody buggers up the settings and ruins a bunch of photos for you.
Review your trophy photos quickly before collecting animals to make sure you got that photo that you really wanted. Easy for this to happen in the excitement of it all - too easy to take a few more while you;'re there!!
Your laundry will be done every day, so pack light so you don't spend too much time fumbling around in your bags looking for things.
Be open minded and listen to the team that is guiding you. If they think that this is the best kudu you're going to get, then trust them. If you have specific standards, then raise this at the very beginning of your hunt so that you're not feeling any pressure to shoot something you're not interested in. I tend to have some idea of why I'm there, but then just go for the ride, take it as it comes and enjoy the adventure. One of my best memories was stalking waterbuck - my main quarry on my first hunt - we lost that bull but bumped into a very nice kudu bull in the thorns and changed our focus to him. We spotted him while stalking (one step - look around, one step - look around....), we spent an hour getting into position and we nailed him with an offhand shot at 75 yards. A beautiful memory and I wasn't even chasing a kudu on that trip!!
If you're happy to sit on the truck and hunt from the vehicle all day, you're not suddenly a great white hunter because you step off that vehicle to shoot the animal with your feet on the dirt (2 feet from the vehicle!!). Make the decision to hunt on foot and use the vehicle for the long stretch to get you into the right country, or if you're going to hunt from the vehicle and you're happy with that, then just do it.
