It amazes me to have people say this all the time. I always wonder—how can we measure effort, be it 50% or 100%? Aren’t we evolving as individuals and isn’t our capability to do something being enhanced with time? The extent of our capability is just a state of mind—it’s a thought, a perception of ourselves, what we are doing and what we can do.
Let us completely ignore the idea of “percentage of effort”. Let us, instead, focus on getting something done or in more specific words “giving what it takes to get it done”. In retrospect, you can measure by your own means whether the effort you put in was your 10% or 200%. It is just a mere statistic that you can use to further develop and enhance your skills.
