Working on a budget for a 20K per year salary.?

So I may be getting a job with a hospital-based EMS service as an EMT-B in Oklahoma. On the low end I'll be making about 20K a year working two 24 hour shifts a week plus whatever part time job I get. The job also gives great benefits (health, disability, insurance discounts, continuing education credit and such). I have a vehicle (2008 Jeep Wrangler) which is paid off completely so all I'll be paying is insurance. Im also planning to upgrade to paramedic after a year of B experience and the hospital subsidizes the cles required (translating to more pay and job opportunities). So is it possible to live comfortably like this and what's a good recommendation for budgeting a low salary like this? Thanks to anyone who answers.
