According to the Hadith it is not good to plan for the distant future.

Answer

Toolul Aml (cherishing long and distant hopes) is a spiritual malady. It has different applications and meanings for different people depending on the degree of their Taqwa and Islaah. What is toolul aml to one person may not be so for another person. There is no standard barometer for this. Rasulullah (sallallahu alayhi wasallam) said: "When you find yourself in the morning, do not be concerned about the evening, and when you find yourself in the evening, do not be concerned about the morning." Obviously, everyone is not able to adopt this prescription.

As you progress spiritually, you will understand the degree of toolul aml which is reprehensible for you. This is not an issue which can be satisfactorily explained with examples. It depends on the type of bond a person has with Allah Ta'ala.
