I am also poor like a college student. Actually, poorer since at least in college-first-time I had 3 campus jobs and didn't have grown up bills like car payments and car insurance. They actually want you to pay that ish every freaking month. Did you know that they are still touting that crap that you're supposed to spend two hours outside of class for every hour in class? Do these people understand the real world and that most students are working their way through school? Ridiculous.
With a brand new schedule, adjusting to studying and adjusting to a much, much, MUCH tighter budget - clean eating and working out have been super tough to work on. And guess what - believe it or not, they are not at the top of my priority list. *Oh shock and disbelief!* Hey, we all have lives to lead. And these things can't be number one all of the time for everyone. You know what? THAT'S OK!
It's ok to not get it right straight out of the gate. It's ok to take weeks or months to figure out how to make a healthy lifestyle work for you. You can't come down on yourself for not being the model fitness citizen in 24 hours. That's ridiculous. If you give up because you can't be perfect, you're much worse off than if you keep pushing through and figure it out. As long as you're actively making an effort and not just sitting around and complaining without actually DOING anything, you're headed in the right direction. All you have to do is just keep going.
