“I manage my frustration in a healthy way.”
"Frustration" is defined as "an emotional response to stress." It's a common feeling that everyone will experience in their life. Some people experience frustration in the short-term — like a long wait in the grocery store — but for others, frustration can be long-term, like stress at work.
Another way to think about Frustration, is in relation to "Attachment": Frustration arises when there is significant attachment to a imagined/desired state, object or outcome (future/past) - that feels "unattainable" (estimation of required time, effort, ability - or strength of connection/relationship) from the perspective of the present state. In this view the solution to frustration is simple: Be present.
