It’s a wall. Your options are to go over, around or under it. I guess you could even give up and turn back if that’s your inclination. But getting mad at the wall for existing accomplishes precisely zip.
It’s perfectly natural to feel frustration, but that doesn’t mean it’s helpful or productive. Frustration is anger combined with powerlessness – but you are not powerless. Never.
You have brains in your head, and feet in your shoes. Frustration is what you feel when a solution has not yet presented itself, but the feeling of frustration is the very thing preventing a clear solution from manifesting. If you need to walk away from the wall for a minute, do so. But screaming isn’t climbing.
In other words – get over it.
