More than just a German figure of speech which means something like;

no problem, everything is fine, it is easy, Kein Ding (no thing, nothing) is also

a new way of thinking, learning methode and life philosphy 

which can help you find answers to your own questions,

deal better with the day to day challenges of life, and 

gain insight into the true nature of the most important things in life,

Kein Ding is based on the fundamental idea that

the best things in life, such as love, freedom, peace, joy, truth, change and wisdom are not things

that exist in the world outside of us, they cannot be found, lost or acquired with money,

but they are free, and at the same time the most valuable and important things in life.

These things are human qualities and virtues that exist in each and every one of us.

Only there can they be found and developed, in order to be then applied practically.

To express it with the words of John Stuart Mill, an 18th century British philosopher:

"Human nature is not a machine to be built after a model, and set to do exactly the work prescribed for it, but a tree, which requires to grow and develop itself on all sides, according to the tendency of the inward force which make it a living thing."

Kein Ding was inspired by prophets such as Jesus and Buddha, the holy scriptures, the big names of the American self-development industry such as Deepak Chopra, Wayne Dyer, Napolen Hill, Dale Carnegy and Anthony Robbins, philosophers and psychologists such as Erich Fromm, Krishnamurti and Carl Jung, as well all the countless thinkers and visionaries who tried to find answers to life's fundamental questions.
