I feel like I've became something else now.
When I was a teen I was a true aries, full of energy, adventure, stubburness, heroic and unstopable.
Did I mention, not only I'm a ram, but in chinese zodiac I'm also a goat.
That should make me extra stubburn.

Anyway these are my likes and dislike that makes me unqualify for an aries.

1. My favorite color is green, yellow
2. I like peace and harmony, I love meditating
3. I am careful, cautious.
4. I'm a slow driver
5. I'm perfectionist, I get irritated when I don't get what I want.
6. I'm very organized, when it comes to group project.
7. I don't want to be a leader of the group, I just like to support.
8. I feel, I care, and I'm sensitive.  (not gay)
9. I love to study life, and I can just sit in one location and enjoy the peace all day.

You are more than your Sun Sign.  Check out your whole chart.  There may be other influences you are moving towards.  

They say arians are much better when they grow older most of the negative traits just fade away.

sounds like you just somewhat became a capricorn...

I understand this, I think maybe in some way you've evolved to become a better Arian?  Or clusters from other signs are becoming more dominant in your Arian sign?  We are still learning about how signs affect us in more ways than one, maybe with the universe changing nothing can be set in stone, it is the same for star signs to change and evolve along with the universal patterns??

Maybe tigers do change their stripes?
