The greatest discovery of my generation is that a human being can alter his life by altering his attitudes of mind (William James). Now I guess, the Buddha discovered that a couple years earlier. But it´s still great to know that we´re not the slaves of our minds and feelings.
A Positive Attitude may not solve all your Problems, but…
… it will annoy enough people to make it worth the effort.
I think that especially applies when you’re German.
