I have been looking for work for quite some time now. I feel pretty beat down, as do a lot of people out there. Nothing is worse than the feeling of being worthless or not good enough.
I have found a way how not to feel worthless. If you are not good enough for their business then they are not good enough for yours. Don't spend your mighty dollar there, go somewhere else. Even if it is a place that depends on donations to pay their employees. If you were not good enough for them, then your donations are not good enough. Is it a grudge? Could be, but after all it is just business.
