Its going to depend on your sponsor and your momentum. Im a "work the steps quickly as possible" kind of guy. My philosophy is get through them once to "stop the bleeding" or get a quick foundation if you will. Then continue to practice and expand on them as you grow spiritually. I have never seen anyone go back out from working the steps too quickly, but in just 5 short years I have seen countless go back out because they lost momentum or were unwilling to move forward with the process.
the important thing is that you are thorough and leave nothing out intentionally.
Best wishes to you!
