Answer:
It would be absolutely heartbreaking to have a dream and not be able to achieve it. If that ever happened to me, I would definitely feel put down. However, I would try to move onto another job as swiftly as I could. I would pursue a job that is based on my interests and fits into my daily schedule. That way, I could work in an area I am comfortable and happy with. Hopefully I am able to achieve that.
