Live the Pareto Principle lifestyle:

Relationships. Who are the few people that have the most positive impact on my life? Spend more time with them.

Priorities. What are the few actions that have the most positive impact on my day? Prioritize them.

Learning. What are the few information sources I learn the most from? Focus on them.

Stress. What are the few sources that cause most of the stress and friction in my life? Eliminate them.

Just have one good day. Then repeat.

Research has shown that once a person believes in a particular aspect of their identity, they are more likely to act in alignment with that belief.
