The Terminator actor announced last year that he will release his personal memoirs in October 2012.
Schwarzenegger has signed a deal with publishers Simon & Schuster for Total Recall: My Unbelievably True Life Story, to be co-written by author Peter Petre.
The former California governor took to his Facebook page to ask his followers if there are any "stories or themes" from his life that they would like to read about that he may have forgotten.
"I need your help," Schwarzenegger wrote. "I have been working on my book, Total Recall: My Unbelievably True Life Story, for quite a while now, and later today we are having a brainstorming session to talk about themes, stories, and ideas I might have missed.
"A million minds are better than a few, so I'm asking you to let me know: what do you want to hear about? What themes in my life? Are there any stories you really want to hear? Give me your ideas. You can all consider yourselves my co-writers."
Schwarzenegger is currently filming The Tomb with Sylvester Stallone, and will also appear opposite his longtime friend in The Expendables 2 this summer.
The action star recently stated that he would be interested in making a rumoured Twins sequel with Danny DeVito.
