Good Thoughts. Just to add:
If Possible, Do chanting/Writing bare foot in one sitting or standing posture!
Never do chanting forcefully, Condition your mind and spirit and increase duration but gradually!
If You Pray/Chant for any other, Don’t make him realize to get obliged.
If Pray, Thanks to God that he allow you to recite thy holy name. Don’t expect Lord to thank you for your devotion.
Try to Chant without any desire in mind. Still if there is any purpose behind chanting, Accept the decision of your destiny wholeheartedly.
God can change destiny, But only if it is beneficial for all concerned. Don’t use wrong methods like excessive fasting etc to force Lord.
Keep surroundings and area where you chant, Clean and pure!
Let there be light while chanting, Feel the presence and light of Lord!
Chanting should never be used to demonstrate your level of devotion. This is personal relation between Lord and Thy Devotee/s.
At Last Numbers are not important. Once calling Sai with Love and complete surrender is enough instead of writing thousands of time without any emotion.
May Baba Bless All of Us!
