My budget

Right now I am having a big change in my life and this is affecting all areas in this moment, like my budget, school, time management, and responsabilities. I was without a job a little longer than a month and I had to use the savings I had to pay my bills, fortunately I got a job a few weeks ago at Sprint. With this new job I am having positive changes because I have a money entrance again and I can now pay all my bills and start with my savings again, less gas since my job is closer to my house than the one I had before and my cell phone bill went down. But I am also having negative changes such as changes in my schedule, working more hours, and right now I am about to go to training for three weeks, this is fundamental for my job, this means I am going to miss class and is going to affect my grades, but without a job I cannot afford college so I have to make this sacrifice and try to make it work, do some extra credit and do all my homework. I have not received my first pay check but I think is going to be 1,600$ dollars each month and this are my bills…
