Living with yourself
On the one hand, it seems just a very small percentage of people are truly ready to accept changes. But on the other hand, an enormous number of them are dreaming about it.
The only reason there are so many different courses, mentors, and especially books about how to change a life, become successful, and so on.
But the path from dreaming to execution is usually completely different. It is easy to buy a book, even read it, but it is hard to follow every single piece of advice from it. So the next step is to buy another or take a course. That's why the "success market" is so big, but there are not so many truly happy people around.
The root of the problem is internal fear. Dreaming is easy, but execution is hard. Once you decide to make dreams come true, you will definitely face reality and your internal fears will finally be satisfied.
Beating the fear might be easy if you just accept what you really want. not dreaming about something, but wanting it for real. Live with yourself. Accept it and take action. And fear will disappear.
