Difference between December and January Caps?

I've never met a December Cap once in my life. Only January ones and they were on the Third decanate. What are the December ones like? Are they like the January ones or are they something completely different?

My grandma is a december cap, 31st.
She is a bit of a pessimist and loves to complain but I have always got along quite well with her even though she can be racist as ... something. Don't really like that side but all of the family from my father's side are like that unfortunately.

I think January Caps are a bit more balanced.

I admire my granny, who is a January Cap. My sister best friend is one too, and she's a sweet heart. I think more of the no nonsense attitudes come from the December Caps...or maybe people are rubbed te wrong way more by the Dec Caps? My cousins father is Dec. 28th and he is much more firm than my father who is Jan. 16th...or 17th. When I was younger he(my cousins father) didn't play when it came to my grades...he stayed on me much more than my father did. He also managed to argue with everyone much more than my father. My father is more of a people person. For the most part, everybody likes him aswell as my aunts Jan 11th husband. He gets along with everyone too, and is pretty friendly.

All of my mother Cap exes, were January Caps. I didn't like any of them. My best friend is a Dec 22nd Cap...I don't like him either, so i personally don't see the difference when it comes to the men.

I do notice though that January Caps are more successful.

Or maybe not more successful, but more focused with purpose.
