I realized I was back, back to the hustle of real life and hard choices
"I realized I was back- back to the hustle..."
or
"I realized I was back to the hustle..."
But at the same time I was excited and ready to jump back into a life I'd missed and a future concealing my next adventure.
Omit "But." Maybe look for another way to say "life" since you had said that the sentence prior. You can use a metaphor for life. Or, "...I was excited and ready for the next adventure, whatever it may be." Something like that.
It wasn't until after I had the opportunity to tour the campus that I fell in love with CMC's focused, relational, small school approach to education .
"It wasn't until after a campus tour that I fell..."
Walking with my tour guide, both times, the comradely of the school was apparent.
Both times? Huh?
It was a reminder of Chile and the children I taught.
"It reminded me of my experience in Chile and the children I taught."
Show more confidence in your writing; be concrete in your statements about yourself. Try to show more how our experiences in Chile relate to CMC too. Also, a few spelling and punctuation errors but those should be easy to fix. Not bad! Good luck!
