It's a simple statement, but just thinking about something does not bring about your desired result. Mark Joyner, the creator of Simpleology, uses the following example to illustrate this point. Let's say that you wanted a drink of water. Literally take a glass of water and sit it in front of you. Now, think these thoughts
"I want a drink of water."
"It would be nice to have a drink of water."
"Please, Mr. Water, come and fill my belly!"
[Make-up your own thoughts here]
Ok, did you try it? What was your final result? Thinking + no action = no results. Now do this. Reach out, take the glass in your hand, and take a drink of water. How simple was that? In this case, thinking + action = desired result.
"Nice illustration", you might say, "but the action required for my thought isn't that simple". Not to wear on your nerves, but my response to that is, "So?" So your thought requires more than just one simple step. Why not determine what the steps are, write them down, and then take the first step? Then you could take the next step and the one after that until you have achieved your desired result.
What have you been thinking about lately? What's stopping you from taking action to bring about your desired result?
