Undergraduate / UBC essay about my diary as the most important thing to me [2]

My diary
I wanna know if my response is way too personal for a university essay or not?

What is important to you? And why?

(maximum 250 words)

My day is never over without telling her all its incidences. She's the protagonist of all my success stories; before every future step, she displays my previous ones to proofread. Whenever I'm on the borders of a new challenge, she awakens my success memories in my mind, motivating me to work hard to the bones to conquer it. In my down moments, she always embraces me, pushing me to back up myself and eagerly continue my path. On my feeling-worthless moments, she always encourages me and reminds me of all the hard moments I've experienced before, making me believe in my potential to pass this one too. Her birthdays' gifts are the best; they always show me how the new-versioned me is compared to the old-versioned me. She's my best companion and the reason behind every conquered fear and achieved success.

My diary is God's gift to me. Waking up in the early morning, experiencing joyful moments, stressful ones or even a daily routine, I end up expressing my feelings and reciting my day down in it. It's my pace growth mirror; every time I open it, I learn from my past steps, whether a failure or success, and I feel more focused to take bigger steps.
