Scholarship / Describing myself as a student, family member, and as a person or individual. [4]

Uhmm, I have an idea in my mind right now.

It's like this, I will start my essay with: I describe myself as a double beam balance. and so on and so forth...

I have some ideas in my mind to come up with.
I mean would it be alright if I use some metaphor and or simile in my essay?

I'd promise that I will soon type the whole essay.
