When in pain or loss, at times it feels like a lot around you has happened against you. But when you successfully cross that period and step into a better day, you feel good about yourself for having crossed the hurdles strongly and successfully. The moments of deep sorrow from past appear very normal and less intensive when you are surrounded by success.
Knowing all this is something important but realizing all this is a good experience to have under your kitty. Because, what you know is may or may not be what you act as. But what you realize makes you act a lot better.
