Kind of work i plan to be doing in 10 years, both in my career and community - Scholarship Essay

Based on my current achievements and interests, I need to write an essay describing the kind of work I plan on doing in the next 10 years.

I am an undergrad with interests in in science (chemistry in particular) and maths to which i have applied to the chemical engineering major.
300 word limit and the deadline is on the 2nd of March.

Essay: I have always been fascinated by chemistry and science in general as a child, and with mathematics and physics being a strength I possess I have gotten to the conclusion of choosing Chemical Engineering as being my primary major.

After having made a great deal of searching about the major and it's work areas I plan on studying for the first 4 years at the university while also participating in an internship program. The experience I'll receive from the internship would be of great aid during my studies and ultimately after graduating which is when I would have learnt about all of the possible mistakes that could happen during the internship rendering me prime and ready for job opportunities, the minor accompanying the chemical engineering major will either be; French as learning a foreign language insures job security and gains me a high degree of cultural competence, or a science minor complimenting chemical engineering which could help me concentrate in my studies in the underlying discipline.

After graduating with a bachelors degree in engineering I'll hopefully find a job in a process or nuclear energy related industry where I can have an economically stable lifestyle.

- it's 195 words and unfinished, any help on structure, grammar and a conclusion is very appreciated..
Thanks in advance

After having made a great deal of searching about the major - you could've just said "after having a hard time considering which major to choose.."

..which is when I would have learnt about all of the possible mistakes that could happen during the internship - I'm not a pro about scholarship essay but "possible mistakes that could happen" sounds too pessimist for me, maybe you can find another word for it.

That's it for now. Good luck!

Thank you for your reply, do you think the essay is done or is there something extra i could write as im getting a feeling I should write more.. :)
