Ambition will change due to situation or vice ??

Yes i believe that a person who has ambition might start off with one dream in their heart and end up with another depoending on their life circumstances. I know from my own experience that when i was a little girl, like many other little girls i wanted to be a nurse, but at the age of five i was told that this would not be possible for me because of this problem i have with my eyes, well of couse the doctor who told me this was quite right, and so throughout my life i have had this sort of thing where i have dreamt of doing something and i have actually allowed people to change my life for me by using my eyesight problem as an excuse, well no more of that so now i am living totally for me and to no one elses wishes for me. I am doing a degree at university in earth sciences so that hopefully if i get the grades i can train in volcanology, no one will stop me anymore.
