How to create it.
I added a YouTube video but in my situation I didn't watch any particular vlogger. It was a simple start, in the beginning, I wanted to track my water intake for a month. So I used stickers on my planner page. Each cup of water was marked with a sticker on that day. Eventually I wanted to track other things.
To make your own you need three  things. You can determine the intensity or its simplicity.
Something to represent a "tick" mark.
Somewhere to mark it.
Someplace to post or put it.
How to use it.
When starting, I suggest you keep it simple. Don't try to HT twelve  different habits. Start with two . You can use it to HT a current habit like 'drinking water' or a desired habit such as marking your AB or Plank challenge. I think the biggest habit to incorporate is to remember to mark your HT daily.
Why do we need it?
First of all let me give you some background. At some point in my life I was trained and worked as a Chiropractic Assistant [CA]. Than I took it to the next level and became a Registered Nutritional Consultant Practitioner [RNCP] in eastern and western nutrition. It was my job to reveal the report of findings, basically what the DC found. Aside from the car injury clients everyone else would get the, "If you change a few habits" speech.
That resonated with me since so many of our diseases [Dis-Ease] are connected to life-style. This was the beginning of my holistic journey. A time in my life where I read labels, considered what I ate and where it came from. Unfortunately I had already loss a lot of loved ones to diabetes, heart disease and lung cancer. My mission was to help those around me. Did they listen? Not always because they refused to change a few habits. And when they finally decided to make a change it was too late, since the desire to change was the result of a doctors persuasion. Which typically resulted in a bunch of drugs and weekly visits.
Do we need to wait for a WAKE-UP call on our health or can we maintain wellness?
