Always know what your next meal is going to be.
If you know what it is, then you’ve thought about it in advance. If I’m starting my day at 8 a.m. and I’m not finishing until 8 p.m., then I don’t really have time to do anything. I could just go over to 7-11, and eat something crappy because that’s what is available to me.
I can think ahead, Hm, I’ve got a long day, so I’m going to make a juice in the morning and pick up a kale salad. That’s really going to get me through the entire day, and when I go home at 8 p.m., then I’ll make dinner. You need to think about it in advance.
