<prompt> Human: So in my last year of high school age 17, I started working as a programmer. Since I was ensured with a roof over my head, with food and water, and all the basic life necessities, I didnt spend much of my salary. Now Im graduating high school with just a bit less than half of my yearly salary in the wallet, when everyone else of my age still sucks money out of their parents.Im not a great money-waster, but I do sometimes get in the mood of Ill pay for you all, so dont hold yourselves back.How can I ensure myself to not waste everything on some stupid purchase or pointless experience? Although its not much money on global scale, for my country its enough to stay healthy and fed for another year. Paying for my studies wont work, since I can get in for free with my grades.  <response>: self control.nothing special about it.
