The process of knowing starts with humility. Accepting you are not sure enables growth. Invest time to better understand the outdated ideas affecting you. Accept the power you have over life.
There are seamless shades between every idea. Very little is black or white. Your power over the world is in how you percieve it. Change your perceptions and reality effectively changes.
Stepping outside your ego allows your experience to feel better. Instead of good things and bad things, there are just things.
Learn that ego-distancing and you try more things, which leads to finding what you like. Generate the brain patterns that teach to accept what is.
