Are you stuck in the middle of a long project that is important to you, but there is no deadline, nor any related urgency? Maybe you do have a deadline, and you just can't seem to muster the will power to get it done? Perhaps something is taking far too long than it should, and you feel some internal interference in getting the job done?
There's hope!
One way to look over the situation is first to make sure the solution you are seeking will actually resolve your problem.
Defining the problem becomes very difficult if there are multiple problems contributing to the situation. With long-lasting, intractable problems, this is almost always the case.
Case in point: someone's room is always messy. This is at least a three-part problem. Space problem, habit problem, aesthetics problem.
There must be space, a proper place, to put each and every item in the room. If not, the room will be messy.
If we don't take the time to put things in their place, the items won't be where they are suppose to be, and our room will be messy.
I have to like how everything looks when it's in place. I have to like it so much that I will actually take the time to put it back the way I like it. Otherwise I have no motivation to manage to keep putting things where they belong.
To slightly modify an old adage; A place for everything, everything in it's place, and I'm highly satisfied when it's all in place. If any one of these is lacking, the room will be perpetually messy.
If this doesn't resolve the issue, it could be the case that the solution you are trying to implement won't ultimately accomplish the goal. This is where Solution Troubleshooting and Motivation Troubleshooting come in.
