It all depends on what you consider "work" as in "work-load" and how much free time (& energy) you actually have- & still be able to keep up with whatever the rest of your life involves- that's not something we can answer for you, I'm afraid.
To get the "best" out of our pets, I think we need to spend quality time with them- beyond just slinging rodents & cleaning their homes. Otherwise they just become a chore.
I'd stay out of breeding unless you're planning a serious effort in that direction- it takes luck, skills, & the right investments to make money selling. Without that, you may only break even or even lose money.Living creatures can have health problems, equipment can fail, & not everything is "meant to be". And breeding-& selling takes a lot more time & energy. That's a whole different question than just adding one boa, lol.
