Here's one more thing. I'm not new to swimming in open water in that I grew up swimming in lakes, but am new to swimming with intent in open water, if you see what I mean. I found it very helpful to take Wahine's advice to sight every sixth stroke instead of what I'd heard before, which was just to sight occasionally. Sighting that often and regularly seems to help keep me feeling oriented, whereas if I only sight occasionally, I often go through a "Oh, where the heck am I now?" brief confusion.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
