If you think you are putting in 99.9% efforts and there is no much difference between 99.9 and 100 think again. (let’s not talk about the poor souls who put in less efforts)
If it’s 99.9% then
It is missing 32000 heartbeats every year
It is 20000 lost mails every hour
It is 2 unsafe landing of aircrafts every day
It is 1000 errors in surgeries performed by doctors
We take things for granted as it does not affect us directly. Only 100% means commitment. Excel in what ever you do…100% excellence..
