An undying patience can only go so far. This client would be close to seeing my exit sign for the final time. Don’t allow clients like this to soil your good name. If you are worth your salt then the fault lies with them. Tell them to give you one week of documented solid effort. If they really put in the work (and you WILL be reviewing this work), then they will undoubtedly see the results of their labor. If the fail to adhere to the plan, point that out and explain why their methods aren’t following your expectations. If they still blame you, show ’em the door and spend that time helping someone with more accountability. Tough love… yes, but its love for yourself at least.
