On projects You do very well when you have a project with a start an end date. For example, with your first book you were able to bring tasks to completion with ease and wake up crazy early to do it. You were motivated not only by the beginning of something new but the prospect of finishing it so you could start another project. At work, you have some new projects and you seem to be happier because those tasks are clear and they have direction and even a start an end date. You can see the end vision even if you don't know the full impact it will have; which is okay! Always give yourself a project, at least where it's appropriate. For example, people are not projects. You should not treat them like some sort of puzzle or intellectual challenge—they are people. In addition, obligations don't have to be projects, either. Laundry is very simple and takes no more than five minutes of effort at a time—why turn it into anything more convoluted? Even your writing practice doesn't always have to be a project. You could give yourself writing prompts that are detached from the rest of your work and seem to have no significance rather than being connected to some larger task. Or, you could frame a daily practice as a project, like you have with your reflections project. (Who are you writing those to?) Perhaps you could practice creative nonfiction writing by writing ninety days of stories from your day-to-day experience. That would make a small task into a project and possibly easier to achieve. No matter what, you do well with projects, so take advantage of that even if it's a psychological ploy to make you focus.
On spaces You seem to enjoy being in the office after hours, left to your own devices. It's fun, and you get time to be in your own head to work on your own thing. The space that you're in—the noise from the bars below, the quiet inside the room when nobody is there, the little amount of light peering in from the streetlights outside...it creates an atmosphere in which you're able to do great work. You should recreate such a space wherever you go. Take care to put yourself in a good spot to do your work, your reading, or your writing. If you are distracted, move elsewhere. Much like sleeping, putting yourself in a good physical place is a proactive way to make yourself happier and more peaceful as you work on whatever your labor consists of.
