"Fail to plan, plan to fail"
Keep a to-do list. Update it. Review it. Put on a couple of easy wins.
But be honest with yourself.
If you haven't done one of the items on your list, then ask yourself why not.
And then ask yourself what you are going to do about it.
Are you going to drop that item because it is no longer relevant, because it is too hard (yet), or because you have an obstacle to overcome first?
Use your plan to plan, and then see that plan through.
