Reflect on issues and events that happen during the day. Examine different situations and think how you could have handled them better. Try New Things next time you encounter that problem.
Practice Until It Becomes A Reflex
Some information becomes engraved in your mind, the neurological pathways formed and overall the information is very durable to the point where recalling it and acting on it become a reflex.
Recalling information over and over, practicing it over and over is so important to mastery.
Actively challenge yourself
Did you do really do x,y or z correctly? Is there any other way people do things? Can you take some inspiration from them.
Create goals
Use reflection to create future goals. When thinking about a specific event, upon discovery that there is a better way for that event to have been handled, create a goal in your mind (or vault) to next time attempt the new solution.
