I read a finance book recently that said "Highly productive people control and channel all energy gotten from emotions and other feelings to other important aspects of their life which have proven to increase efficiency, re-direct their thoughts and produce better results".
The ability to master our emotions and channel them properly is very important.
The mind also is a powerful tool. Even the Holy book says " Guide your mind with all diligence for out of it flows the issues of life". This has helped me so far in life.
Thanks for this educative post. I enjoyed reading all through.
