It’s an interesting question this. Something that some of us dread.
Why? Simple… For me personally, it reminds me of childhood dreams that were stolen; dreams that still I strive to achieve. Some of us tend to change our dreams as time goes on; moving with the tide or the times as you will. But others do persevere and overcome so many trials and adversity to get their dreams come true. One thing to note. A dream that you don’t fight for will haunt you for the rest of your life.
All that said, it’s an interesting question to ask in a job interview. Most of us would not be prepared to answer such a question; yet alone answer truthfully, when you’re out there to get a job out of necessity rather than pure passion. 😛
