How to write regularly?

Trying out a writing challenge. 30 posts in 30 days: The next 30 days will not mark a full calendar month or some other sort of temporal meaningfulness. The only reason I use today, is that I have despite all the good advice not yet managed to create this every day routine. Which is just generally difficult for me–heck I am glad if I remember to moisturize! So beginning today gives me four days (including the weekend) where there are no excuses for not writing. It’s basically a little bit of a head-start.
