The Environmental Factor?

I just came off lunch with a rather pesky question in mind. As my friend and I were twaddling while gobbling away the rather tame lunch, we veered off a topic of the general lethargy that has seeped into our life because of leading the high life of being a Software Techie. What he said next has enlightened me so much so as to bring back my almost-dead-and-buried-blog back to life. I would like to sum up the statement as, 'You are only as bright and engergetic as your work environment'. As much as I would like to dismiss this statement nonchalantly, taking a nostalgic view of my own life has led me to admire the profound meaning in the statement.

The more I revisit the statement matching it with experiences of my own as well as others, it seems rather strange but the statement does seem to be true.

Could this really be true or am i being fallacious?
