Friday’s Finds

On every second Friday, since 2009, I review what I’ve noted on social media and post a curated selection of the best finds. I do this as a reflective thinking process and to take some of what I’ve learned and put it on a platform I control: this blog.

Book Reviews

I regularly review books that I have read and feel are worth recommending to others. Writing a review forces me to reflect on what I have found is important.

I sometimes receive free books from publishers.
