Has your dream been changed or not?
(Have your dreams changed, since you were a child?)

When I was a child,I wished to be a scientist. I want to be a doctor or a teacher as I grow up. However, things go contrary to my wishes.

(I once dreamed of being a scientist, when I was young, either as a Doctore or a teacher. But things have not quite worked out that way.)

Food science which I find that it is not my favourite was chosen as my subject in university. Sometimes I regret doing such a silly decision, but it is useless. Not can all the objects be return back.
I recently know what I want to be and which I love. I love drawing

(To follow my initial dream , I had chosen Food Science at Unviversity. I now come to regret this as I come to discover my love and passion for drawing) 

(I think I could be a good architect , like my Grandfather , who was very successful. But I feel it will be very tough to now follow my dream of what I love)

and I wish to be a architect. Maybe I was effected by my grandfather, for he was a successful architect as well. I am sorry that the thing is hard to be done if I become an architect.
Has your dream been changed or not? Do you stick to it?

Food science, which I found out was not my favourite subject, was chosen as my major at the univeristy.  (Did you choose it?  If so, then "I chose" would be better.)

Good

Maybe I was effected by my grandfather, for he was a successful architect as well.
Maybe I was influenced by my grandfather, for he was a successful architect. (No "as well" because that means you are an architect also.)

I am sorry that the thing is hard to be done if I become an architect.
???   I'm not sure what you mean.  Perhaps:  I am sorry that it will be so hard to become an architect.

I changed my major a lot.  Even when I didn't officially change it, I took some courses in different subjects just because they were interesting and not because I needed them.  I think my parents thought I was wasting time and money, but in the end I see that all of those "extra" classes were important to my education and to getting me to my current career.

I think a 16, 17, 18-year-old is too young to be required to make a decision about his or her career.  If you don't have some experience with the different areas of study, how will you know what you like or don't.

Good luck in following your new dream!
