Sometimes frustration comes from disharmony from something that is not aligned and should be in harmony.
Sometimes frustration is an alert to figure something out, find a resolution, seek harmony. Find the solution to leave things better than how you found it.
Frustration means it’s not easy or simple to figure out. It might not be complicated but is difficult to see.
Sometimes it’s allowing yourself to endure the frustration until time gives you awareness to see the solution.
