Set up your work conditions to be ideal, in terms of space and time. Develop your scholarly base; have all your work materials that you need on hand when you work. Sharpen your pencils.
But don't wait until everything is ideal to start working. Work anyway, because there will always be conditions that are less than ideal in some significant respect. For me, for example, I often don't have the book I need on hand. I could be more organized, but I am not. Somehow I out-publish people who are much better organized because I don't let things like that bother me and I don't make excuses for myself.
