You can have all the opinions you want, but uninformed opinions simply aren't as valuable in a targeted forum. That's just a fact of life (that I would think someone with your experience would have realized by now). And in an open forum like this, you will be called out for spouting ill-informed opinions in situations where informed facts are preferred. I've worked alongside nurses, but I don't think I have the right to go to a nursing forum and tell aspiring nurses what their job prospects are going to be like, based on my opinions. Can you see how that would not be well-received? Being near something, and actually doing it, are different and not equal, even though both can produce opinions. Does that make sense?
Honestly at this point I'm feeling like this is more basic life advice than an MD vs. DO thing. Your experience will be valued and appreciated by many people in many situations. It can and will help you. But you are going to have to realize its limits, or you will not foster goodwill in a process where you will need it. You will need to learn when to put on your "experienced nurse who is a leader and supervisor" hat, and when to put on your "aspiring pre-med" hat. In other words, situational awareness.
I really do want you to be successful in whatever you try for.
