Wanting is what the conscious ego thinks it needs.
Needing is what the sub-conscious ego (the id) thinks it wants.
We need something when we sub-consciously believe that it is necessary.
Something is necessary when our conscious ego decides it wants it.
Problems occur when our wants and needs are in conflict.
When we are in doubt and conflict as to whether our wants and needs are necessary, then our id and ego are not congruent, and we are sub-consciously creating resistance to our conscious desires.
Conflict between our conscious and sub-conscious self is procrastination and will always result in opportunities being missed and problems being created.
Our Soul and Inner Coach is never in conflict and always knows what its Self really wants and needs.
The Soul has no distinction between wants and needs, and sees all new choices as opportunities for growth.
