you say work is humdrum: Nothing is humdrum ...Arnold Bennett
...How to live on 24 hours a day
Arnold Bennett
Nothing is humdrum, if you think and troubleshoot to understand the cause and effects -
of situations and people;
Focus on thinking cause and effects using the 7.5 hours of Non-work
My note:
Human Being is a cause and effect machine. If you are bored, pick an effect that you are observing - issue or opportunity - and go about understanding what could be the potential causes and proving out the same!
You will improve your curiosity and your resourcefulness!!!
