I think there might be more steps, I think buying a film body and shooting film for a while might be the next step.
To answer your original question, yea sometimes it is worth it.
Mostly true... here's my slight revisions:
Shoot only in JPEG - Check
Discover RAW shoot in both JPEG and RAW - Check, but then I couldn't figure out how to process the raw file using my existing software... so back to Jpeg with periodically shooting in raw + jpg with the assumption I would eventually figure out what I was doing.
Become a RAW purist and shoot only in RAW, use excuses like someday I might be able to redo a picture that I thought was lost, my processing skills get better etc... Some of the excuses are used to cover poor or sloppy technique behind the camera- I screw up periodically, but it isn't poor technique... just status quo with me being negligent... regardless of the format.
One day discover that not all of your shoots need to be in RAW. Not all subjects and situations need to be improved on.
Consider once again shooting in RAW and JPEG so you do not waste time having to process pictures that are "good" enough.
Find out that you are wasting time sorting out your JPEG's from your RAW and wasting memory on the computer.
Shoot which ever is appropriate at the time.
I'm shooting at full raw and med-jpg... but the med-jpg is just wasting hard drive space... so I might drop that.
