Experiences with a lesson and advice that resonates can become guiding life rules.
Life Rules Can Be Simple
Don't overthink a piece of advice that fits you. Add it to your list. I've heard something in a podcast, read a line in a book or article, and failed or succeeded at something that triggered a learning insight.
Simple Rule: Identify your fear and then act.
Life Rules Can Be Complex
Your rate of revelation for 1 rule may come in pieces. It could be taking 2 or more values and combining them into a way of behaving which becomes a rule.
Complex Rule: Realize when you're fence-sitting and then determine to take action or postpone action to a SPECIFIC time.
This one started with "realize when you're fence-sitting", evolved into taking action, and evolved again into setting specific dates for taking action.
Capturing Your Life Rules Insight
Keep all of your rules in one place and make sure it is easy to capture additional ones. I use Google Keep - it is a convenient and simple option. Use a notebook, or whichever is your preferred personal knowledge management system.
5 of my Life Rules:
Avoid over-attachment to thoughts.
Connecting others is a duty of success.
Investments in learning are never wasted.
Have a minimum standard of acceptability.
When thinking emotionally, ask if you are making up a story for lack of information.
