<prompt> Human: Within the past few months, I was 2,000 GBP into my overdraft because I had to pay someone back some money. As a student, that was hell but Im glad to say that my account is in the positives with some hard work and a few side jobs and Ive limited my overdraft back down to 500GBP as it used to be. How do I Prevent this from happening again  <response>: Dont buy sht, you dont need !
