When Lisa Allen boarded a plane to Cairo, she was completely oblivious to the fact that she was going on her most significant transformation of all time.

She was then 34 years old, severely overweight, boringly suicidal, freshly dumped, and smothered in nicotine addiction.

Life was starkly getting worse for her, spiraling by the minute.

Yet, within two short years, this lady changed from a heavy smoker to losing over sixty pounds of weight, running marathons, earning a degree, and completely changing her mind.

So what really happened?

It’s not willpower because she didn’t really touch anything higher than fortune. Lisa didn’t get superpowers like the other people around her.

She entered something much more accessible-and far more powerful.

The study of habit change.

Her journey is one of the key elements featured in Charles Duhigg’s bestselling book “The Power of Habit,” but more importantly, it’s the inspiration that comes with that teaching.

So, let’s break down how Lisa rewired her brain one habit at a time and how you can do it, too.
