A budget itemizes the expenses and sources of revenue. There are two essential features of a budget that a decision maker keeps in mind. In the first place, the budget documents the cost of the change. Anyone faced with the prospect of fixing up an old car recognizes that there comes a point beyond which one more additional expense no longer adds to the value of the car. In the second place, a budget must balance.
Decision makers maintain control of the projects by controlling the budget.
If your plan requires a change in the physical, objective world, then physical force may be necessary. Something must be moved, altered, fixed. Labor must be expended. If a mind, a destructive attitude, messed up values, or false beliefs need to be changed, then persuasive talent mat need to be employed. If those mired in problems were able to extricate themselves, they would.
