I don't think you will find a particular "life style" associated with keeping ball pythons. If you look at the membership of this site, you will see there are a wide range of people who keep reptiles. Some are young and just starting out, but many are older and more established. I think trying to peg or generalize too much leads one to step into a trap. We shouldn't try to put people into little boxes but look at each one as an individual. In fact, if there are any common characteristics of ball python/reptile owners is that they are very individualistic or independent thinking people. I also am a motorcycle enthusiast. However, if you met me during the workday, you would be surprised to learn that I have reptiles and motorcycles.
As far as Achilles Heels, my opinion is that irresponsible owners/keepers are our biggest threat and weakness. That is why I participate here and why this forum is so active, because others feel the same way.
Since I've acquired my BPs, my evenings and weekends have changed. Last night, I came home after working a long day and had to work on converting babies over to f/t, clean rat bins, answer emails from potential buyers, update records, etc. It made for a very long day. In addition, we have guests coming this weekend, so tonight will be another long night cleaning snake bins. Many people will tell you that breeding ball pythons is easy. I'm not one of them. It is fun most of the time and I enjoy our animals. But, it is work.
