Think of a period in time in the past when you felt happiest. For me it was my early 20s. What were you doing regularly that made you happy at that time? Do more of that. People that are happy do things that make them happy more often. People that are unhappy usually don’t do the things that make them happy often. 

 Make babies I guess.  

 Are you not sexually active anymore? 

 I am. I'm taking about having babies. That is something that brought me a lot of joy. My kids are grown now. So your comment got me thinking, maybe I want to have more kids.  

 Do you have children? 

 I do not 

 Do you plan on it? I assume you are younger. It feels like procreation is one of the best things we can do here.  

 Eventually when/if I find a good partner that wants a similar lifestyle
