Two Strategies For Decision Making

It states that motivation requires simplicity and clarity. 
Any complex flow chart or decision matrix decreases your chances of success. A clear outcome and resultant progress also improve your confidence.

Expectancy Theory

“Once I made a decision, I never thought about it again.”

When the commitment is 100 percent, your future behaviour is already set in stone, with no back-and-forth struggle and revisiting of the decision-making condition.
When your best friend offers you a Coke, you know very well that the decision to not have anything like that is already made, and it is easy to say no.

Setting In Stone Future Behavior

Clear-cut, zero-tolerance decisions and self-commitments are better than having to decide every time, or committing conditionally.
A 100 percent decision is better than a conditional decision, which can lead to decision fatigue and waste your limited willpower.

100 Percent Commitment

“We are kept from our goal not by our obstacles but by a clear path to a lesser goal."

If you are only 90 percent committed to your goal (like following a certain diet, for example) you have to ask yourself and test your commitment multiple times a day.
You end up unable to predict your behaviour, and any future outcomes. By having a loose commitment setting in your mind, you are bound to deal with decision fatigue and see yourself repeatedly fail, lowering your confidence.
