What Are Personal Boundaries?
The limits and rules we set for ourselves within relationships and our lives. A person with healthy boundaries can say "no" to others when they want to, but they are also comfortable opening themselves up to intimacy and close relationships.
There's a healthy balance between work and life, consistent energy levels and a sense of fulfilment as opposed to exhaustion and burnout.
A person who always keeps others at a distance (whether emotionally, physically, or otherwise) is said to have rigid boundaries. Alternatively, someone who tends to get too involved with others has porous boundaries.
