You are driving then suddenly the vehicle in front of you pull an emergency brake and you instantly press the brake of your vehicle and it stops just an inch before the front vehicle. You shall say "phuuuh!!, how lucky I am".
Did we ever noticed that in life this lucky situations happened to us many times? Alas what we remember most are always the unlucky one. Actually we are many times luckier than not.
Only if we looked down we shall see lucks are all over ourselves but if we look up we shall see only otherwise filled our life.
