It is said that it is bad for your health to get attached to objects. And I do agree, but there are two things which have helped me to get where I am today. No matter how shitty I'd felt or how bad the world seemed at the time, I'd put on my earphones and I'd inmerse myself in a book. I'd simply stop existing and the time didn't matter. I could smile.
Then I got back to reality. And again, no matter how shitty I'd felt before, I could smile again. Reading and listening to music are the one thing that keep me happy no matter what. They are my batteries.
