Contents of the blog can be decided into two types.
The first one is unplanned entry. When a idea occurs to me, it produce one entry. material of this type of entry is news on the web, tweet, what I see during walking, and so on. Nothing special is not a problem. Habit of writing is important for me.
Second one is elaborated entry. It has special value for blog visitors. Indicating certain example is a little bit difficult since they are special.
One profitable way to gather material of my blog is to carry note about me. While walking or doing something, write any idea regardless of its quality every time some idea occurs.
I can substitute note for Smartphone. buy smartphone as soon as I can after the entrance exam.
