Is it normal to only eat once a day?

I never eat breakfast because i barely get any sleep during the night and when i wake up only a couple of hours after going to bed eating breakfast is the last thing i feel like doing. I usually use my lunch break to finish my homework or nap in the library. When I get home at about 5 i eat ramen which is usually followed by something like steak with mashed potatos. After that I sleep until 10 - 11 and when i wake up i start working on my assignments. im not trying to lose weight or anything, i just dont feel like eating most of the time.
