A break
I am the type of person that among so many obligations I have a hard time taking a break, I prefer to finish everything at once. Of course that leaves me exhausted, so I need things to keep me energized.
What I can never deny in the middle of the study is this delight, coffee and chocolate, they are indispensable to be able to continue, and even to concentrate me.
My study nights are mountains of chocolate, many cups of coffee and good music :). Who accompanies me?
