Describe your short and long-term goals (working as a cardiologist). Related?

Please help me make this essay better, anything like errors, suggestions. Am I on the right track here?

In life, every human being has an ambition; ambitions that are most times set extremely high and sometimes low to a point the individual can achieve it. I have always set my ambition as high as it could ever be.

All my life, I have had different ambitions one being a teacher, architecture and another being a lawyer. But my goal has becoming a cardiologist. My mother has heart issues but she has never had a heart attack. Her doctor that part of her heart is swollen and any tension or constant thinking or anything could trigger her to die. My desire to become a cardiologist is because of my mother. It upsets me to see people enduring heart diseases. I aspire to take care and better the wellbeing of people as many people with heart diseases as much as I can. I plan to major in nursing first and earn my Bachelors. I hope to acquire a job as a nurse and use the money I earn to provide for myself through medical school to become a cardiologist.

In order to achieve my long term goal, I plan to learn as much as I can to be prepared for college and I plan to graduate from high school with cum laude and attend a university that will help me achieve my goal. Another accomplishment that can help me achieve my goal is working towards receiving scholarships so I can afford my education. If I achieve these short-term goals, I will be able to achieve my long term goals of working as a cardiologist and making a positive contribution to people all over the world.

Sorry but I'm not very good at grammer so you'll want to have someone check it!

i think that you're missing a word in this section

i could be wrong, but I believe that "nursing" should be capitalized since it's a profession.
