When things go your way, you continue what you’re doing because it works. If events aren’t what you want, you need to change something.
An honest assessment is necessary. Pay attention to what’s going on in your life. What are your actions? What do you expect to happen? Are your expectations reasonable, based on the results of your actions?
Trial and error helps you develop a sense of realistic expectation. As you learn what works, your expectations become more experience-based and you can predict results with greater accuracy.
To change what happens, change what you do. The best action may not be evident, but continuing a type of behavior that doesn’t work certainly isn’t the answer. Try something different. If that doesn’t work, try something else. You can really get your life on track this way. Learning by experimentation worked when you were a toddler. It will always work.
