Run through these checklists allocating priorities from A (very important, or very urgent) to F (unimportant, or not at all urgent). If too many tasks have a high priority, run through the list again and demote the less important ones. Once you have done this, rewrite the list in priority order.
Recently, The Art of Manliness provided an historical look at checklists, along with a detailed primer in deciding which lists will work for you, culled from the excellent, The Checklist Manifesto. You can implement the same routine in your daily work to help give you a greater shot at success.
Mastering procedural processes and repetitive tasks with checklists allows you to focus on the larger goals at hand. It’s the minutiae of the workday that can be easily forgotten at the detriment of other important projects.
You may find it easier to compile several checklists (covering personal, study, and workplace, for example). Try different approaches and use the best for your own situation.
