For some reason I do not fully understand, I actually like this essay and think that it is suitable. Albeit it's it not perfect, I think it coveys a true sense of introspection, a trait that ad comms really look for. The ability to evaluate oneself objectively.
Secondly, I think that your thesis paragraph at the end of the essay shows that you actually bring something into the mix, something in the form of your perceptions. There is a saying that real diversity doesn't lie in the color of one's skin but in the content on one's thought.
To bring diversity on our own is not possible, but to create something new and distinct with other people, the process of melding minds, flying sparks of intellect, the engaging reactions, all that is beautiful.
All I would suggest is that you highlight this a bit more because it is an amazing observation. Diversity is not possible in an individual, only in a group of individuals.
Also,
instead I can and I push myself into the thriving sea of interactions.
is a bit awkward. probably try rephrase??
All together, I like this. its risky but sometimes risky is good.
Good luck :)
