In life nothing really is free - all is the result of conscious efforts

Happiness is the result of ongoing conscious efforts to love and to improve love. All those who have achieved more have done more. All those who have achieved a better world have done a better job. All those having created a peaceful environment have established peace with all others first. All those living in a loving environment have loved more than others.
YOU are the only creator of your world - of your life and thus your entire eternal future. You decide how life will be and whatever is now is the result of your past achievements. If you wish your life to be different, then you have to change yourself first, then your life and environment will be different.
