Why 3? Let us answer this question first. Studies show that 3 is an ideal number for the mind to easily remember things. The human short term memory can retain 3 things easily in one go. 2 don’t say enough and 4 is too many to remember, so 3 it should be. It makes your point or sentence emphatic, effective and memorable. Three makes for a beautiful pattern. The first time you say something, it’s an incident. The second time you say something, it’s a co-incidence. The third time you say something, it becomes a pattern.
