ALBERT EINSTEIN WROTE THIS RIDDLE EARLY DURING THE 19th CENTURY. HE SAID THAT 98% OF THE WORLD POPULATION WOULD NOT BE ABLE TO SOLVE IT.
An effort could be defined as a highly conscious exertion of power or simply, just a serious attempt to achieve a target success.
The easiest classification of efforts are based on the resulting effects, which means ineffective efforts and effective efforts. Ineffective efforts are failed attempts on completing a task. Adjustment is required so the task might be made up successfully under another effective efforts.For those who are on a short-term goal, effective efforts appears as a set of tactic actions that result in immediate noticeable changes. For instance, a college freshman try to adapt the new study environment by changing his learning methodology, that could be timetable control, subject distribution, etc. On the contrary, those pursuing a long term-goal need to put their best efforts on strategic decisions. Indeed, such decision-making at certain critical points may affect their whole career or even the surrounding society as a chain consequence. For example, a city mayor approves a planning project on river navigation reinforcements. The effect of this policy would not be visible shortly, yet its contribution is undeniable over the next generations.
Another way to categorize efforts are based on its popularity. Well, there are, indeed, both well-known amazing efforts and forgotten devoting efforts. A street artist may sample the first case with a twinkling grafiti work on the main route wall in the centre of a city. Obviously, amazing efforts go with glory, victory, honor and wealth that can be found in stock dealers, rock stars, or sport players recently. On the other hand, devoting efforts are performed silently, even with neither cheering encouragement nor materialistic supports. Scientists, army sodiers in special forces, etc mostly represent this case. There are thousands of significant discoveries each year, however, there are just a few awards like Nobel, and hardly noticed by the world media. Who cares about those geologists that prove a geological thesis about earth origin lately ? And Stephen Hawking is less popular than Tom Hanks. Such comparisons above just show the characteristics of these two kinds of efforts.
To conclude, the awarded bounty shall deserve the effort makers with a view to encouraging more contribution ; yet there is always triggered leech in every society.To succeed is to risk, yet to put an effort means not to risk but to earn either experience or achievement.
