I will say that I don't bother figuring out macro-nutrients (protein/carbs/fats).
As a vegan, everyone is always so concerned about how I will get enough protein. Everyone except me, that is. I have plenty of muscle mass, so clearly I get enough protein without worrying about it.
I do scribble down everything I eat in a notebook, though. That is enough accountability to keep me on track. I used to RABIDLY count calories, but it brought out the worst of my OCD tendencies and desire for "perfection". I think calorie counting is a great overall method for other people though, and it works perfectly for many, many, many people.
Just my personal experience, you may find you do better tracking your percentages and other things more closely.
