Some questions for nurses?

Hi, I'm new to this site so if I put this is the wrong category I apologize. I would like to get advice from nurses, because I don't really know anyone that's a nurse and it would help me out a lot.
So I've put a lot of thought of becoming a nurse, I'm in college doing my pre reqs. I decided I wanted to do this because helping people makes me happy, I like thrill/excitement, and I want to make a good living to support myself and family.
Lately I've been having doubts, because I'm not sure I would love this career once I had it.

So these are my questions:

-Do you love or regret your career of nursing?
-What was your life like before, and what's it's like now being a nurse
-Did you have the same doubts?
- What's your opinion of qualities that you think nurses should have, and what weaknesses do you think are a deal breaker?

If you have any other advice please feel free to share (:
Thank you soo much in advance.
