I've already posted two questions regarding this(here and here). I've gotten excellent answers but I'm still confused and this question, I believe will answer all of my doubts.
Could someone who has done a PhD or is doing it, share his/her experience? Give an overview of your full experience from the first day till the last day. What did you do in your first year, how did you choose your topic, how your advisor helped you when you got stuck, how doing the Phd developed your problem-solving skills, etc. Please include technical terms when they help you get a point across. For example, if your PhD was related to building a quantum computer, include terms like qubits, etc.
Basically, just walk me through your PhD, so that I get a good idea what exactly one does in a PhD, what sorts of problems does one encounter, and how your advisor helped you.
