Long term versus short term

I wrote an article about how some of our experts predict the coming of a financial crisis, but we still cannot avoid the crisis. In the article, I say that people are impossible to precisely know the precise timing of any future event. However, when we are coming to face the real world problem, we have to know the precise timing of certain future events, as we have very tight time constraints.

Do we have any solution for such problem? In some occasion, we treat some immediate issues and assume the factors will stay the same. Because the difference is smaller when the time gap is narrower, then it is better to solve short term problems and accumulate them to form a long term solution. Such solution is very reasonable and easy to do. However, the solution may not be the real solution. When we split a long term issue into many short term issues, because when the time gap becomes narrower, the changes of important factors are too small to be taken into account, but the small changes accumulate over time, when it comes to the end of the time period, the changes of the important factors become significant to affect the result.

This is what happens in our markets and economies, we pay a lot more attention to the short term major changes, but much less attention to smaller changes over time until people notice the accumulated significant changes.
