Something to write about

Stephen Fry and Hugh Laurie. I'd like to describe some impressions I have of their work.
What do I usually write about? Some major principles are as follows:
1) I write mainly about what's really interesting to me or moves me. Or delights me. Or what I consider worthy of attention, valuable or interesting. Frankly and sincerely.
2) I try to put in in an interesting and readable way, do some quality writing, so to speak.
Sometimes I wait for the appropriate mood and the appropriate amount of time. The mood is very important. If I am tired I can't write long and finely worked out texts.
So again a post which is not very interesting.
