How to start an essay

The start of an essay is usually an introductory paragraph.  This consists of several sentences that provide an overview of the topic and explain your thesis or argument.  It is often easier to write the body of your essay before writing the introduction and conclusion. 

“Memory addict, with regard to the past” is not a complete sentence and makes little sense.  When talking about memory and thoughts, “addict” is not a word that fits.  One might be consumed with their thoughts of the past, preoccupied by their thoughts, or lost in the memories of yesterday, but not addicted to memory.
