Let's not come with reasons such as we do not have enough time, or we do not have a good memory power. We have to fit this noble project into our schedule, as the virtues and bounties that comes with are numerous, and inshAllah, if done with Ikhlaas, then Allah will reward us in both the worlds. And, about lack of memory, yeah it could be true if one had to memorize any other text of science or poetry, but not for the Qur'an. We should have a firm belief and understanding that it is the Power of The Kalam (speech) of Allah that enables anybody on the face of earth, who desires to memorize it, shall be able to. We should concentrate on doing our part, and Allah will make it more and more easy as we go along further. Allah says in the Qur'an to Our Prophet Sallallahu alaihiwassalam:
سَنُقْرِئُكَ فَلاَ تَنسَى
We shall make you recite, so you shall not forget. (Surah Al-A'laa: 6)
Which other book in the world has been memorized by people, word to word, verse to verse, exactly with the same intonations that our Prophet recited, to whom Allah SWT had revealed it so! Which other book is read so repeatedly and the reciter never gets bored of it, unless Shaytan overpowers him- and the more it is recited, the more beautiful it is, and the reciter is in more awe than ever! SubhanAllah, this is one of the many miracles of the Qur'an. No matter what some enemies of Allah and His Dheen do (like burning of the copies of Qur'an etc), there are many thousands of people (even non-muslims) on the other hand, who learn and understand the Qur'an. Even disbelievers like Abu Jahl, Al-Waleed Al-Mughirah were addicted to its beauty, and would go and listen to the recitation of The Prophet hidden in the darkness of the night. SubhanAllah.
4. Atmosphere: We should try our best to avoid all kinds of distractions like phone calls, children, munching on some nuts or crackers during this time. This again takes us back to the previous point where the morning hours are the best, since there is less distraction at that time.
