Hello! I hope I'm posting this thread in the right subforum. As in the thread title, I'm 31 and I currently work a low paying job. I have a partner of nearly 10 years who is about to graduate as a registered nurse and enter the workforce. At the moment my income supports both of us and has enabled her to focus on study but when she commences work as a nurse I'll have a golden opportunity to pursue an area of study without having to worrying too much about supporting myself whilst doing so. I can't imagine that many, if any, of you have worked on a chicken farm but you can take my word for it when I say that it is something you wouldn't want to do for the rest of your working life. I live in Australia so I can only describe the educational system as it is here. I'm starting from scratch, or at least it feels that way. I left high school early which means that before I even think about going to university I will need to catch up by doing Year 11 and 12 studies. I don't know what area of physics I am interested in yet. I've been reading about relativity and quantum theory and I'm excited by it and very keen to learn in more detail. I realise that mathematics is the framework for physics but I don't feel put-off by that aspect. I want to learn. I want to study hard. But, again, I'm 31. I don't really expect there to be some arbitrary answer to the question of what investment of time I should be prepared to put in. At the back of my mind though, there is the nagging feeling that it's too late for me to be tackling something like this.
