Habits

I am not sure this is really true or not. But it makes sense that it takes some time for the neurons to rewire, whether it really takes 21 days or not is open to debate, probably it depends on the habits in question.

Reading and exercising are already part of my habits. I don't need much prodding for me to pick up a book or go to gym -- they happen almost automatically to me. Writing, however, is quite a different thing: I always use the excuse that I need a good chunk of time to write something down, which is probably not true. Maybe it would be a good and fun experiment to keep writing something down for 21 days -- I will see if writing will become a habit for me by March 22nd.
