If somebody knew every time they did something it was going to be a hit there would never be any failures. Sadly, that's not how it works. You take nothing for granted.
It is the activity of the intellect that constitutes complete human happiness - provided it be granted a complete span of life, for nothing that belongs to happiness can be incomplete.
There is one thing, and only one thing, in which it is granted to you to be free in life, all else being beyond your power: that is to recognize and profess the truth.
Families, particularly, tend to be the ones that you take the most for granted. They seem to slip under the radar, all those important things - it almost becomes second nature to do so.
