There are only two things that we as humans are fully in control of.
a) how we interpret what happens to us.
b) how we respond to what happens to us.
The interpretation side of things = being in control of your own thoughts.
The response side of things = being in control of your own actions.
The two are obviously linked. There is nothing else that we are fully in control of.
This what Steven Covey was driving at and what MMM highlights in this post -
http://www.mrmoneymustache.com/2013/10/07/how-big-is-your-circle-of-control/The law of attraction is good if it teaches people to be in control of their own thoughts rather than bumbling along on autopilot feeling really unhappy and not realising they can do something about it.
It does however get dangerous if people buy into the law of attraction to the extent where they believe that they can influence the weather, the stock market, the lottery, getting a new job, falling in love etc, simply by sitting around and thinking about it.
Positive thinking has to be linked to ACTION. That is where the Law of Attraction in whatever guise (The Secret is the one that most people know) falls down. They don't talk about CONSISTENT ACTION on a regular basis.
I'm sure I've read something somewhere about scientific research on visualisation. The findings of the studies basically concluded that visualising what you're going to DO to get to the end result was far more productive than simply visualising the end result itself. Visualising the steps you're going to take is better because it acknowledges that you actually have to DO something, and encourages you to start planning properly rather than mere wishful thinking.
Who gets wealthy? The guy that implements MMM's advice on a consistent basis or the guy that thinks about the universe manifesting $100?
Who learns Spanish? They guy that goes to classes, studies and takes a trip to Spain, or the guy that simply visualises himself speaking Spanish?
