Look to enhance the marginal benefit in whatever you do. After a while additional time spent on a particular activity doesn’t yield results in terms of efforts made. There is an inflexion point till when rewards are a multiplier with respect to time given and efforts made. After that, it evens out. Have an eye at the inflexion point. Instead of giving more time and effort in the said activity, identify something else which can produce more results. This will help you become a super achiever.
