Boundaries around your mind is to stop you from wrong not restrict you from the right. Maturity keeps changing and so should you. Tell me, how can you relate to the characters of a previously read book to a book you are reading now? Why do you want to? Believing in the beliefs you had for yourself when you were 16 and then carrying and believing them when you were 16 and a half, is wrong! Six months are enough to change your mindset! Beliefs work great but they don't work forever. You don't even have to make them work if they aren't useful anymore. It's using an empty fevicol bottle to stick the envelope. maturity and beliefs often get in a row. Maturity changes with experience, beliefs have to be changed as per that. Change your beliefs when you know you are atleast a bit right. Tying yourself to a same belief always won't help.Things change. And so do you.
