Undergraduate / Thoughts on the start and revising the use of "I" (the sonography field) [2]

The essay must demonstrate the applicant's perspective on the field of sonography and why he/she is choosing to pursue it as a career.

I am excited that I have found a career that I know I will enjoy and will be passionate about. For a while I have been searching to find my niche in the medical field. I began my journey in pursuit of the career by taking prerequisites for the program. Throughout my courses I became captivated by the design and science of the human body. I found myself wanting to soak up every bit of information I could possibly take in. This encouraged me to press on toward the goal of entering the program for sonography so that I could begin to put into practice all that I am learning.

The next step in my journey was to shadow an ultrasound tech. Standing there I watched as the transducer put images of an actual human body on the screen (in front of me??). The excitement within me grew as I saw a liver, a kidney, and then I saw the blood flow of the vascular system.

This is what I have so far. Any help is appreciated. Thank you.
