I'm not much but I'm all I have.
The trouble with being educated is that it takes a long time; it uses up the better part of your life and when you are finished what you know is that you would have benefited more by going into banking.
One thing I've found that I can do that I really enjoy is rereading my own writing, earlier stories and novels especially. It induces mental time travel, the same way certain songs you hear on the radio do.. The whole thing returns, an eerie feeling that I'm sure you've experienced.
