My strategy was simple - every night, before bed, I would make a schedule for the next day. I planned out when I would attend class, go to work, run errands, and do chores. Writing things out hour by hour, I could keep track of how much time I spent on each thing - so I could avoid getting distracted and off track. Checking the weather also helped insure that the next morning, I wouldn't be standing in front of my closet wondering what to wear.
My schedule soon expanded to include other things I needed to do daily - but often skipped over - such as drinking enough water, eating enough fruit, and exercising. By forcing myself to write everything down, at the end of every week, I can look by and change the amount for the following week based on how well I did.
I decided to make a digital template of my schedule - one I use consistently [inside of writing on random scratch paper] and can print on half a sheet of paper to store.
