I always feel the need to chime in.
You're a teen. You live with your parents, you work at a pizza shop.
Over the next few years, your life is going to change dramatically. That's a good thing.
The best thing you can do, for yourself and your eventual snake(s) is to give yourself the freedom to allow your life to change in whatever way it needs. It'll probably change several times over and in three years you'll look back and be amazed how far you've come.
Not only don't get a snake, don't get any pet, don't get married, don't take any loans (except maybe student loans), don't let anything tie you to anything or anyone. Ride your life and see where it takes you.
Anything that ties you down now is only going to retard and prevent your development.
You'll never be more free than in the coming few years. Embrace that freedom and ride it for all its worth.
When its over, you've found your niche, and you're settled, fill your home with snakes.
