I got married (answers both questions, I'm afraid). I often wonder if that is a really bad way of doing things since I tend to simply do what my wife wants. If I want "me time", I need to tell her in advance so she can put it in my schedule. However, I've always been super easy going in that respect. My wife loves organising things and trying to optimise stuff so that everything fits. She even optimises the meal preparation so that we
never throw out any food (it's a miracle as far as I'm concerned). However, on the weekend I often want to cook and my wife will say, "I'd like paella. Please use up the mushrooms, milk, sauerkraut and pickles". So, I have to be pretty creative.
To be a bit more helpful (because I don't really want you marrying my wife -- it would be inconvenient for me), I think the real key is to ask yourself why you want a schedule. Where are the places you are hurting? It might be better to address those pain points directly rather than trying to overhaul your approach to living life. At least as far as I'm concerned (being very easy going in this respect), there is nothing wrong with not having a schedule. In fact, it is completely liberating. However, you need to have priorities and make sure that your priorities are addressed.
