hold your plane and start walking forwards with it, move the stick and watch the surface, no think carefully to when you drive along and stick your hand out the window, everyones done that and which way does your hand go when you change its angle, so now look at your plane and think, now, if i was the wind, which was would i push this if this thing here went up/down.
now you got it, and you also have a simple understanding of orentation.
