That statement seems contradictory of itself. Several experts with similar experiences will usually have minor differences in approach, but they will agree on the more common aspects of a problem a newbie is experiencing. This type open ended question that was posed at the beginning is so broad and vague that the dicussion could go anywhere. Perhaps narrowing it down to a specific issue will guide people in the discussion, for example, engines, sport flight, pattern flight, glow plugs, landing approaches, flight line operations, etc. Otherwise, it is like nailing jello to the wall or trying to hit the broad side of a barn.
