Did I promise 45 days?

I think I said something about 45 days to a friend...
Why?
Do I need pressure?
Do I need anything or anyone from outside?
Or is writing really just your inner process.
And totally irrelevant how long it takes?
I have a concept for a great weekly/bi-weekly or monthly column.
I had a great idea for a new book.
I have many ideas.
Execution? Anybody?!
Sigh.
