I don't like this approach. If everyone were to approach a problem with this mentality it would conjure doubt in the entire process. Nothing would ever get done. Question: "how do we know if anything exists?" <--(an extreme example). Answer: "well we don't but it doesn't help us with the realities of the problem at hand." I think this idea introduces confusion and does more harm than good, in my opinion.
this is one of the main reasons I drifted away from healthcare and towards engineering. It's hard to deal with limitations that seem purposefully aimed at preventing you from getting the job done, and done right. My time on earth is limited and so is my patience.
You're just in the process of coming to terms with change. The only advice I can give you about that is this: Recognize that change is not something to be afraid of. It takes courage and certainty to choose because no one can make a choice for you. You will be accountable for the path you take. The choice is yours. Like you said, indecisiveness leaves you getting nothing done because you know that you have to make a choice. I believe the silver lining you're talking about is the decision you're most eager to make. Think about it as long as you have to but the worst thing you can do is to not do anything :)
