A lot of comments talking about having kids for purpose, so I thought I'd add mine. I don't have kids and when I compare myself to other friends that have kids I can see how having kids can add purpose (to some extent).
That said, personally I have found immense purpose in life by having a dog. My dog not only makes me happy he teaches me that it is okay to do mundane things in life everyday and still feel extremely happy and satisfied. Each day I look at him and I thank him for being there, for teaching me how to live life, how to love unconditionally and how to live in the moment. I know it's silly but I'm having tears of joy as I'm typing because he is sleeping right next to me at my work desk. Love you my best friend ever !
