I live in three main states of mind. From having asked a few people, I imagine that the same is true for most other people.
The first is when you feel fully immersed in what you’re doing. This feeling of being in the zone usually emerges when you’re doing things that you find very valuable, like spending time with a loved one or working on something that is aligned with your goals in life. Since this is a state of high emotional engagement, you can only be in this state for a few hours a day.
The second is when you feel relaxed and good. You’re not immersed in the details of a specific activity, but instead are observing and reflecting on what’s going on around you without trying to achieve a specific goal. This is a state of lower emotional engagement and, as a result, you can spend most of your time during the day in this state if you take action to minimize the time you spend in the third state.
The third state is when you feel distracted. This is usually the result of another underlying feeling, like fear or anger, whose root causes you have not yet taken the time to understand. As a result, you have yet to see the opportunity in the situation which you currently perceive as a threat. Once you spend the time to do so, you can once again return a state of feeling relaxed and good.
A great day consists of being in the first state for as long as the physical limits on your mind and body allow, while spending most of your remaining time in the second state, and minimizing the time you spend in the third state.
