(OOCly, I'm really quite persuasive. I was on the debate team in high school, I'm a published political writer now (editor of NYRA Freedom, a monthly newsletter read on four continents), and people generally believe me, but my "persuasion" is more "manipulation" than "bluff." I'm not a good on-the-spot liar - I have no poker face - but I'm a master of the long con and getting others to do what I want. As for willpower, I can keep myself awake for days on end by force of will alone, my willpower is sufficient that I don't often give in to temptation, and peer pressure is meaningless to me. People often describe me as stubborn.)
I greet the other navigators in my usual slightly-too-polite, somewhat-foreign way.
I take my meals whenever I can, like Donald advised, and make conversation with anyone who cares to. If I hear anyone singing working songs, sea shanties, and the like, I listen in - they're a bit of a hobby of mine (1@8 Renfair Songs? *grin*).
I'll do my work diligently to the best of my abilities. No slacking, and I pay attention to whatever the chief tells me to do. When I am not on shift, I spend half of my free waking hours studying charts and maps, and the other half... goofing off, knowing me. Playing my flute, or not, wandering the ship, or not. I'm really quite restless.
When it comes time to sleep, I watch how the others handle their clothes, and do likewise with mine, even if it means sleeping in them unwashed. Gotta get used to the road sooner or later.
Before I sleep, I say my prayers to my Pagan gods, thanking Loki for the turn my fortunes have taken, Thor for protecting me on my now unending journey, Odin for the wisdom to handle myself well. The Gods Who Travel have always seen me through, so I give them my thanks, my prayers always spoken with sword in hand. They are Viking gods after all.
Because Asatru has no god of the sea that I'm aware of, and I'm eclectic anyway, I also offer a quiet prayer to Poseidon through whose realm I find myself passing, that my passage should be safe and my captain should be strong. At the end of dinner, I pour half of my mug of beer overboard as an offering to him.
In conjunction with my offering to Poseideon, I invoke my Influence Luck ability on behalf of Donald, then again on behalf of the Captain, focusing on each of them for a good ten minutes a piece.
Of course, once I notice that I can actually poke things with my mind, I keep doing it, every chance I get, till I can poke things like I mean it.
