or at least nothing different, special, or amazing. The american dream and material happyness/fame and all that is right out the door.
You stop dreaming and striving and just maintain what you got. Life isn't this long, happy, colorful journey like you thought it was.
Not that this is a bad thing- peace of mind is better then chasing the wind- which is exactly what it is.
But still... there is a lack of satisfaction/disappointment.
