'You learn much better in a nice and inspiring atmosphere'.
Have you ever participated in a training that took place in a dark and grey meeting room? How was your attitude towards the training and how long did it take you to open yourself up towards new insights?
I'm deeply convinced that the place where you learn has an impact on your learning attitude and thus on the learning outcomes. Humans are very visual beings. One of the easiest and most promising mnemotechniques is for example to tie imaginary pictures to words while learning them by heart.
