What makes life worth living for?

 Is it our families? Our friends? I've thought about this question for a long time. And I still can't figure it out. I used to believe that the purpose of life was to live each day as if it were your last. I used to not be afraid of death. What changed?
  I want to have a family someday. I want to find true love. But what is motivating me to do so. Honestly, nothing. Maybe there is no purpose of life. Maybe there isn't anything that makes life worth living for.
   what do you think makes your life worth living?
