Graduate / "I wanted to be an Engineer" - My SOP , first paragraph [4]

This is the first paragraph of my SOP, I think this part is the most critical one. It would be great if someone read it and give me some suggestion about this.

I can remember the day, I was asked by one of my most respected school teacher that what my future
plan is to be. I replied that I wanted to be an Engineer. My School teacher was highly disappointed
because in our country the best students specially girls are highly expected to be a doctor because
medical profession is very popular and a way of earning a lot of money. My teacher asked me why I
wanted to be an Engineer. On that early age of my life my simple answer was that I wanted to do
something innovative and creative by which the next generation would be benefited. On that time I
didn't know much about real aspect of life, but it was my dream that I would be a scientist and spend
my life in innovative researching. Still now I am motivated with my dream. I wanted to pursue Ph.D.
admission because I think it is the best choice I have in front of me to make my dreams true.

Thanks in advance
