The Requirements of Achieving Great Targets...
In Ibn Al-Qayyim's Al-Fawaai'd and in it he (rahimahullaah) says:
Chapter: The Requirements of Achieving Great Targets
"Achieving high aims depends upon having a firm intention and a strong will. Whoever looses them will never attain his goals, because when one's intention is firm, it adheres to the plan and if one's will is strong, the servant will walk along the right way that leads to that aim. Having a strong will opens the way and a resolute intention focuses one on the aim. If his aim coincides with the way that reaches to it, he will be successful. If his intention is weak he will not have a high aim. If his will is not strong, it will not lead him to his aim. The whole matter depends upon the will and intention of the servant and they will never be achieved without neglecting three matters:
innovations, which people make.
abandoning worldly benefits and vain pleasures, which hinder him from his way and aim.
purify one's heart from any vain desires that will distract his intention."
