I did my first one near 10 years ago and was posting regularly once per week for about a couple of months.
Then I started a new responsibility and I had no more available time for writing, so I just stopped to post. The blog is still there, is in Spanish and it was mainly about business and economy. I think I would do it better today but I was 10 years younger.

This time I promise I will not be posting that often. This blog is more related to my day job, but the available time is also small.
Hope you find it helpful. This was my purpose.
