If you feel the need to write, write.
If you learned something neat or solved a problem in an interesting way, write.
If you read something and feel like offering more thoughts, write and add hyperlinks.
If you ever feel yourself shadow boxing with random thoughts, I’ve found it helpful to write and sometimes never publish.
If you have any idea at all, start a draft.
If you get tired of editing, post your drafts typos n’ all, you can fix it later.
If you ever sit down to write and the words don’t come out, don’t write. Close the computer. Do something else.
