True meaning of life? To raise your children with as much love as humanly possible. Teach them right from wrong, to be God fearing and guide them through life so they don't make the same mistakes you (I) made.
I learned a long time ago that my life is all about my wife and kids and making them as happy as possible. The mistakes I made when i was young was necessary in order to perpare my children for their journey though life.
Everything else in life don't matter when it comes right down to it.
