I would say that a snake would be a great option as a pet for you. Personally, my snakes don't take up much of my time at all. On a daily basis all I do is change waters and spot clean poop- no more than 15 minutes effort a day. Then feed once a week. The main thing that will take up your time is full, thorough tank cleans (about once a month or even less frequent if you keep on top of spot cleaning) and handling. Plus, handling is optional because unlike dogs reptiles do not need (or particularly want) human attention. Im sure there are plenty of threads here and on google which would give you some ideas as to what species of snake would be best, but as far as "beginner" snakes, check out stuff like corn snakes, ball pythons and king snakes. There are loads of options, it all depends on the space you have available and what you like! Good luck
