Lazy = Tired??

Does lazy equals to tired? to me, i will say YES because i'm lazy to do my sketches earlier, so i end up rushing all the sketches at once, even my back is aching for sitting too long. Other than that i finished the sketches at 3a.m, this caused me have not enough sleep and caused me to be tired through out the day. Well, this is the consequences for being lazy, no one to be blame but myself & the WRONG decision i made.
