"Ruth's coaching has brought me so much good. By asking deeper questions, the mind starts to release better thoughts, insights, answers and decisions. I have also learned to slow down but that does not mean that I am giving up. On the contrary, I have started to find a balance in doing. I have started to systematically bring new ways and ideas of working and new ways of thinking in my life. I have a more concrete structure in my work and personal life. I saw the actions that needed more emphasis and balance. My prioritizing skills have improved a lot."
