The Law of Diminishing Returns -
The tendency for a continuing application of effort or skill toward a particular project or goal to decline in effectiveness after a certain level of result has been achieved.
Most of us get that if we work harder we can get better results. It's harder to understand that if we continue to work at the same level that the silly Law of Diminishing Returns kicks in and we get lesser results. I ran the second run because if I train the same way that I did the last time then I may perform worse. Yuck!
This applies everywhere in our lives. Put the same effort into relationships; you get less over time. Put the same effort into your job; you get less. Lead the same; get less from your team. We don't stand still. We are always moving forwards or backwards. Stay the same and you will go backwards.
What can you do differently to keep moving forwards?
