What is a diary?
Diary is a notebook used to keep various daily records on everyday basis or over the particular period of time.

The components of a single diary entry
A single diary entry must have the following features:
1. Date. For example, 12 August 2010
2. Time. For example: At 7:30 pm.
3. Title/Topic.
4. Description of the event.
5. Personal reaction on the event.
6. A picture or a sticker that is related to event. It's used as an evidence to support the event.

An Example of Diary entry
12 August 2010.   7:30 pm
Today I met one of my college mates at the Market. We studied together at Tukuyu Teachers College from 2010 to 2012. He is currently an independent attorney. In our class, most of us have been successfully employed by the government or self-employed.

This diary entry example gives a writer a chance to remember the event clearly. Of course, reading just one diary entry can remind you of various experiences like a friend, the location, and various emotions attached to the event.
Writing is not a talent. Writing is a practice.
