Writing Feedback / Grandmother taught me to read - the grammar in this short essay? [5]

My grandmother taught me how to read at a young age. Ever since, I've loved to read. To me reading is more than just learning, it is also an escape. I read whenever I need a break from the world and all its problems. The words of the authors give me a new world for me to delve myself into and for a few hours I am alone with myself. Yet I also read to learn and understand. Reading offers gives us the power to learn things that we might never have imagined. For example, when would I have imagined that our 100 light-year-long galaxy is no more than a tiny spec in the universe? Yet thanks to Carl Sagan I was able to learn that fact and many more facts and ideas. To me all books are portals of the past to help us be better in the future.

thank you!
