There is one thing that defines your body’s state of health. Your body either thrives on it, or deteriorates on it. It’s consistency. Whatever you do consistently will create either health or disease in the body. Consistently means most of the time, in most situations. It is whatever constants you have in your life.
Consistency also means compatibility or harmony. If you stick to your diet during the week, only to let it all go on the weekend, then the only thing your body is experiencing regularly is chaos. If you get to the gym here and there, your body is not holding on to the long term effects of the exercise.
On the other hand, consistency does not mean perfection. Perfection is impractical, if not impossible. It’s also does not mean boring. And it doesn’t mean all-or-nothing.
Yet, you can’t go from none-of-the-time to most-of-the-time instantaneously. Trying to do so is a good way to set yourself up to fall off the wagon. So first think of the self-care habits you’d like to have. Then think about “consistency in stages” to allow yourself to grow into new habits. Master one stage of consistency then move on to the next. Before you know it, you will have most-of-the-time habits.
