To dissect or Not to dissect?

We started dissecting people (dead person) last week. Today is the second time I would be dissecting on a cadaver.
It's weird because I am having fun, but apparently I am not doing a good job at it.
I just dissected the Intrajugular vein because I though it was the carotid sheath. I was wrong and I feel like a great disappointment.

I want to be a surgeon someday but looking at my performance today, am I right for that field of Medicine?
Or maybe it's still too early for me to say?
Or is it the right time for me to see if I am better at other fields of Medicine?

I don't really know, and this is just bugging me.
Hopefully I would find my answer sometime soon.
Ciao.
