I've been trying to read the whole bible for quite a while. I've tried various programs. The bible in 90 days, the bible in a year. I've read Genesis and Matthew about a billion times.
But I've still never read the whole thing.
I'm participating in 365 Days of His Word with Fly with Me, and although I'm definitely not where I want to be, the women who are involved have been so encouraging.
One suggestion was to write down every book of the bible, pray and ask the Lord where He wants you to go, and then read that book. When you're finished, ask again and keep on reading.
