How to trick your brain to create  a new Healthy habit 

When you begin any new self-improvement program, your enthusiasm is high and you're motivated by the pleasure of what you want or the pain of what you don't want. But motivation naturally diminishes with time.
When your motivation wanes, you rely more on willpower. But no one has an Endless supply of willpower. It's a resource that gets "used up." Every time you will yourself to do something that you don't really want to do, you use up some willpower. It's as if every temptation you pass up depletes your willpower reserve. By evening, you may find you have no willpower left. That's why most people blow their diet in the evening after eating healthy all day. If motivation and willpower aren't working for you, there's another way!

95% of our life is dictated by the subconscious mind, the part of our brain that runs our lives on autopilot. This is why you can do everything from brushing your teeth to driving a car without thinking about it. By consciously deciding to create a new habit, you can harness the power of your unconscious to create a new neural pathway. Once a new habit is established it becomes easy to do—motivation and willpower are no longer required.

Once the habit is formed, you can use it to serve as a gateway to bigger changes that can truly change your life. A journey of a thousand miles really does begin with a single step. Stay Healthy :)
