I am sure you have may think that you are of the opinion that the “intent” of the Torah was for us to be happy in life.
However since that is not the understanding of the Pillars of JEwish though (Please see the Mesilas Yeshorim in the Introduction as well as Chovos Halevovos Sha’ar Avodas Elokim) you are simply wrong.
Unless you feel qualified enough to argue with them regarding the purpose of life.
