Dreams and Goals are good things to have.  
Most accomplishments start out as just a dream existing in the mind.  However, Dreams and Goals need to be based on REALITY, which means they need to be based upon a sensible and practical idea of what can be achieved or expected.

It’s not just, “When I’m thin, I’ll look good when I’m dressed well.”

It’s  “When I’m thin, I’ll look really good in a skimpy bathing suit.”….And that fantasy goes on to include changes in our personal characteristics ….  “When I’m thin, I will be the kind of person who struts down the beach in a bikini, making men weep.” …  “When I’m thin, I won’t be depressed anymore.”  .... “When...
