"...Thus, if you come on over, be prepared, and if it is your life's passion, none of the above will matter."
So true and that applies to all professions, not only nursing. I knew one nurse that quit her job to go back as a salesperson, money is less but her passion was in the retail sales. She did not like seeing and being with sick people all the time and she did not like the responsibilities put on her.
Another example, my niece graduated nursing with honors but went into automotive business with her dad instead and she is very happy with her decision.
On the other side, my friend was in computer software business for a very long time. She went to nursing after retiring from her software engineering job. She is now the manager of a non-profit clinic serving low income and uninsured population. Nursing was not her first choice as a second career but she thought she'll try it because everyone seems into it. She learned to love it and the rewards of helping people made it all worthwhile for her.
This I can say, Nursing has many branches you can go to. If you are bored with one, you can try another. There is research or teaching, if one does not like bedside. For me, I'm into clinical (ER and cardiac) and loved it.
Good luck! whatever you decide.
