Op, the answer is HABITS!
Procrastination is a string of small delayed decisions. And habits are the things that allow you to make the decisions and follow through in a consistent way. And once the habits become automatic, you don't have to expend any conscious energy on the "getting started" bit which is the hardest part! You just swing in to action and before you know it, the task is done.
I used to procrastinate dreadfully until I followed Flylady. But having to follow a routine of small actions every day, in the morning and late afternoon, really helped me to realise that one small action leads to another. The worst thing to do is to "wait" until you feel in the mood; because (if you are like me anyway
) you rarely do. But if you do one, small focused activity for 15 mins, or just 5 minutes when things are bad, it usually gives you the energy and motivation to do another. And it's surprising how much you can get done in a short, focused burst of activity.
I follow my own version of Flylady now. I have a computer file listing annual, six monthly, quarterly, fortnightly, weekly and daily tasks. These get added to a written wall plan and a daily tick list on my phone.
Another top tip is to make yourself a "school" timetable on squared paper for the week ahead. Shade in all the fixed activities: 30 mins for getting up and showered, 30 mins school run, work hours, meal times. Then ring fence some things you want to do for yourself eg exercise, hobbies (do NOT skip on this bit because your "me" time gives you energy to do the other stuff). Then literally timetable in the time for housework, the time for meal planning, the time for admin etc. You can set up alarms on your phone as reminders. A good Flylady tip is to allocate a specific day of the week for specific tasks such as Monday = main clean, Tues= planning (meals, holidays, appts) , Wed = anti-procrastination
, Thurs = errands, Fri = cleaning out purse, handbag, car etc etc. This really helps with planning your time.
If all else fails, just do one thing! Anything! 
Good luck
