I have not read anything of Martin Heidegger and I am interested in starting. I understand that "Being and Time" can be very difficult, so what would be a good place to start? (including books by others).
Thank you all for your support. Since I posted this question, I read Being and Time with a tutor where we went in-depth on practically every page. It was a revelation that led me to read other books by Heidegger and incorporate them into my thinking. For others interested, I can share my own experience whereby I would not have been able to understand much without the help of Michael Millerman who tutored me through this process.
Mr White's answer above is very helpful also. I have read the Irrational Man which is an excellent book on the whole spectrum of Existential philosophy of which Heidegger is perhaps the most important part. So that you for this Mr White.
