Whether it’s anger, frustration, resentment, etc… all apply in the following:

There is your frustration with the situation, and then there is the situation.

What you may think is the cause, just might be the effect.

Address your frustration first, independent of the situation.

Often times this resolves the situation. If it does not, it sets you up to solve the situation:

“We can not solve our problems with the same level of thinking that created them” – Einstein
