You fix it by being "bigger" than the problem.
Tony Robbins once reported that we have two conflicting motivations or needs in life (there are more, but I'm concentrating on the first 2):
1) Need for safety, security or predictability.
2) Need for variety, fun or unpredictability.
To balance both of these "needs," you merely become a "creator." You create new ways to have both predictability and unpredictability. For example, instead of cheating on your spouse for variety, try role playing and dressing up as part of your foreplay.
The number of potential solutions is infinite.
I remember one instance of growing "burnout" while working at my first job in the mailroom in Los Angeles, 45 years ago. Working 100+ hours per week was taking its toll. I was able to overcome this by picturing myself hovering above Los Angeles, holding the entire city in my arms. Then I stepped back and held the entire planet in my arms. Then I stepped back and held the entire galaxy in my mental arms. Worked like a charm.
Three years later, while receiving spiritual counseling, I was able to achieve a higher degree of this exteriorization. I found myself outside of my physical body. I could no longer feel the body, the clothes it wore, the chair in which it sat, or feel the air it was breathing. I could see clearly my surroundings -- 12 feet off my body's left shoulder and 15 feet above the ground. I could see the softly-lit, overcast evening sky, the brightly-lit restaurant parking lot next door, and the lightly cracking, pink stucco of the outside of the building in which my body sat on the 2nd floor. I could also see the closed, grayish-blue blinds which blocked my line-of-sight view of my body. Moments later, when I realized that I was not casting a shadow on the side of the building, I suddenly found myself back in my body.
I remember, years later, seeing a track meet on TV. They mentioned that indoor speeds are always slower than outdoor tracks. I realized that the walls pushed in on their attention units. All a runner needs to do to overcome such a conceptual barrier is to be bigger than the building -- to see their body from the outside and run the race with the open sky above them.
Solutions are all around us and within us. All we need to do is look.
