Your first job is to discover exactly what your goal is. What will achieving that goal really look like? Be as specific as possible about exactly what your desired end result is. Your success will be a measure of your clarity – since an achievable goal plan cannot be created around a nebulous “dream.”
My observation is that our minds tend to see the obstacles first those barriers that lie between where we are now and where we want to be or who we want to become. Just as fast as you conceive of achieving your new body, your mind begins to spout out every excuse it can come up with why you can’t attain your goal. So even before we can initiate any action, we literally paralyze ourselves.
