On the other hand, I didn't follow the advice, and instead "Did something I kind of like okay, and can make decent money doing." I've definitely done that, but at the cost of never really chasing down my original dream. Now I'm a crusty old fart and I feel like I could never "do what I love" because I just can't live on entry-level pay anymore--partially due to my lifestyle, but also because I have children, and that's not really an expense you can budget your way out of.
So because I didn't do what I loved while I was young, I've kind of missed the train. I might be able to later in life, but I will have to wait quite a while.
