Have you ever had that dream where you are partying with supermodels on the beach in the Caribbean, living life to the fullest, not a care in the world, and splashing around in the surf with the aforementioned models... only to wake up to find that the water you felt splashing on your face in your dream was just the puddle of drool trailing down your mouth and onto your pillow, and your dog whining to go outside for a walk even though it's way too early, it's raining, and you have to get up in 2 hours to hit the daily grind?
That's an example of the "Dream" and waking up with the "realities" you are referring to.
Have you ever had the dream of walking with your loved one on the beach and enjoying each other's company, when a large lobster walks up and asks you if you can "spare a buck?"... to which you say, "I don't think lobsters should be asking me for change" and then you realize it's not a lobster at all, it's your son asking you for college tuition... then you wake up and realize that your loving wife is still by your side and your 2 year old is sound asleep upstairs with his favorite stuffed lobster plushie??
That's an example of a the "Dream" and waking up to realities that you know you can overcome with proper planning, training, networking, and timing.
Sure, we've all considered it a "Dream" to fly at one point... but the fact is... not everyone wakes up to the harsh realities that you suggested... because they planned accordingly. The way I see it... your eyes will only be opened in such harsh ways, if you followed your dream blindly and with out research or a plan.
