Dreams are life if somebody has no dreams or ambitions that means he/she has no life to live.
When I was a child, I had exceptionally big dreams, one day we were going to visit my uncle's house; we passed by a huge building (it's an institution for research); I told my father and mother that I want to work in this building, they laughed at me and said you have to work very hard to get there and you need to strive to arrive.
My dream was to become an engineer, computer engineer, I ended up studying something else, and never accomplished my dream.
My father wanted me to become a physician, I hated medicine; and I did not study medicine, however, I studied something close to it; pharmacy.
I love pharmacy, I like my job as a pharmacist, but that was not my dream, I shifted my dreams to be successful and have a family and never push my kids to study anything they do not like or want.
