Checklists can be one of the most effective ways to keep yourself organized. Come up with a plan (STEPS) that you need to do in order to finish a task. Make your list.
Figure out how much time you should need to finish each of the tasks on your checklist. Time estimation takes practice- the more you do it, the better you will get at estimating your time needs. This is a strategy that will help you stay on track and know where you need to be.
