do everything in my power so that my children can feel good and have a fair education in all areas of life
People seem to forget that "feel good" doesn't necessarily mean, be happy right now - lifetimes are periods of time and if feeling good right now is going to lead to years of pain and suffering down the track, it wasn't the right thing to do.
I fully agree, feeling good and being happy among other things can be two different things. Moreover, in general I am for the serenity that is lasting, happiness in itself is something that you experience in moments but it comes and goes.
