A final note: don't trust NT trainers for understanding the game, they are usually good at communications (which won them the election) rather than knowing more about the game mechanics than everybody else. I'm one of them. :-)
And while we are on the subject there are situations when the slowdown related to a runaway skill just can't be avoided and you just have to live with it. I am not about to stop training OD for example just because the other skills are lagging.
