Everyone is looking for balance
A bodybuilder is looking to balance a strict nutrition and sleep schedule with enjoying food and going out with friends.
A consultant may want to balance 60-hour workweek with time for self-improvement or sports.
An athlete is out for winning medals but also enjoys studying and thinking about a life after sports.
It does not have to be this or that. The best results come when we combine the things most important to us instead of blocking all but one thing out of our lives. To take a Jungian viewpoint; they never really leave, they are just pushed away and come out as resistance, lack of performance, appetite or stress.
We balance our lives by balancing the different sides that we have in ourselves. Out of this balance we create balanced lives.
