Sometimes the most difficult task in writing is about describing yourself. To be honest it looks little bit weird for me and very though. Anyway, I was looking for a guideline to write a short bio for myself since I had decided to make little bit changes on my blog bio (about) section. I did a Google search and found this link.
I went through the link and read about it. It is very nice and well written. I really like it, however, in my case I wanted to make my bio, author sections more informal and casual. Therefore, what I did was to do the reverse of whatever mentioned in the above link.
Anyhow, it is worth to look at the link even though that you are expert on writing bio. 🙂
