He then identified some evil stuff, which should be avoided at all, to not loose the energy for useless stuff - which is my take away for this week:
Stop wasting time whining - start finding solutions
Stop seeking one to blame - start seeking for the root cause
Stop complaining about $someThing - start acting according to "Love it, change it or leave it!"
Start to make useful breaks at work - no one can deliver 100% all the time
Try to avoid meetings with more than three participants if possible
I don't expect this will free one full day of my week - but it hopefully helps anyway.
