Thought pattern

The Law of Substitution states that one thought, habit, or belief can be replaced by another through conscious focus. It's a principle used in various fields, including personal development and economics, to replace undesirable elements with desirable ones. In essence, you can't directly eliminate something unwanted, but you can replace it with something else. 

Here's a more detailed explanation:

In Personal Development:

The mind cannot hold opposing thoughts simultaneously. If you're struggling with a negative thought, you can replace it with a positive or constructive one. 

For example, instead of dwelling on self-doubt, you can consciously choose to focus on your strengths and progress. 

This principle is often used to shift mindset, break bad habits, and promote personal growth.
