I have everything necessary to work out, but I lack a few areas

I don't have any determination, and when I do get it, I'm too tired, and it's late at night when I get pumped up. I wake up with a headache, feeling tired, and have no motivation. I quit my job at McDonald's to do this, and I don't start college for another month and a half, so I have all this free time. But I live in Arizona, it's too hot, 105 degrees F and higher outside.



I'm slowly trying to get myself to do it, but I just can't for some reason.
