Discipline Yourself !

“...the way a Muslim saves himself in life from lusts and desires and leads a pious life with fear of Allāh, this world is a prison for him because he is fettered in the chains of rules and regulations, while a Kāfir (disbeliever) is free from all kinds of restrictions...and this is how this world is a Jannah for him. The purpose of this Hadith is to induce Muslims for the preparation of Al-Ākhirah (the Hereafter) and prevent them from unlawful luxuries of this world.” [Hafiz Salahuddin Yusuf in his commentary of Riyād-us-Sāliheen]
