Self Awareness Courses

About four years ago ,the company I work sent all of their employees on “self awareness” courses. Each session consisted of groups of about twenty , holed up in a hotel for a week and carrying out a whole range of tasks. This included role playing , confessing a secret to a co-worker, deciding if you were a passive or agressive person etc. I am afraid that during the course I get swept along like everyone else, a bit like a revival meeting. But when I got home I realized what nonsense it all was. Our Company spent about fifteen million pounds sterling on this phscho-babble and I do not think that it made one ounce of difference to our work attitude . Has anyone else been on these course. Did thay think they were stupid or did you benefit from them ?
