To have parallel structure means that within the sentence the same structure/scheme is used everywhere. To achieve parallel structure, I would delete the word being "being" from the end of the sentence. Once you remove that from the sentence, the sentence becomes: "The traits I admire most in a person are honesty, courage, and compassionate." Of course, "compassionate" would be improper in this form, so you would change it to "compassion". Once changing that, your sentence becomes proper and is in parallel structure: "The traits I admire most in a person are honesty, courage, and compassion." Hope this helps you! Have a great day! :)
