The more things change, the more they stay the same...
Whenever I come across the word Disillusioned, it is invariably used in a negative way..
i.e. "He became disillusioned with politics, and chose to change course..."
The thing is, to be disillusioned means exactly that: to be Without Illusion.
To see Truth...
So really, when we become disillusioned with something, we should celebrate!
"I've become disillusioned with my job. I've realized what a complete bag of shit it is."
