“ Two things fill the mind with ever new and increasing admiration and awe, the more often and steadily we reflect upon them: the starry heavens above me and the moral law within me. Emmanuel Kant. „

The core value of Eight Advisory that defines me the most

Excellence

As the saying goes, perfection is never achieved, but excellence is achieved by striving for it. Excellence does not mean always being right.


It means accepting to try, to fail, to start over, to never been fully satisfied, to not disappoint, to remain honest, to always try to do a little more. It also means recognizing and learning from one’s mistakes, putting things into perspective, taking responsibility, and listening to others and to oneself.
