How do you know if your life is fulfilling, money doesn't necessarily bring happiness, but what does?

First of all, you need to be selfless and pour all of your love and protection on your family (when you have it of cours). Guide them, your wife and children become your most valuble charm. That means, working for them to have everything necessary to live healthy in every way, giving up everything that pleases your own body and just live for them and when you have the time and extra money, give to charity in the name of YESHUA, if you don't, then there was no real value to you giving, you just become one in the bunch of people who give sensless. If you do these things in the name of GOD then you will have been fullfilled in every aspect of your life.
