Daniel,
Planning (an aspect of discipline and structure) has been a problem for me, for me it feels like being lost in a maze with a constantly changing maze.
The following has helped a little...
For a structured day I continually added one activity onto my schedule over a period of time.
Discipline and structure can suffer if the mind is not calm -> Deep Relaxation
I also found the Peak Performance Session 2 channels energy and motivation for 'effortless' discipline. Halfway through track 7 I feel a difference with smoothness of thought. (I have noticed that a couple of times).
If you're more right brained try mind-mapping your long term and short term goals into action steps.
Try to find yourself and take control.(does that sound pertinent - for me it is apt)
