Does life feel like a dress rehearsal to you?

I have had this experience my whole life where I feel like I am living the small / pretend / rehearsal version of my life. I feel I am temporarily living this life (living where I am, working where I do) until the time comes along when I will live the big (or real) version of my life. This temporary / small life is not the life I would choose, it’s just a comfortable way to spend the time until the real life starts.

The temporary / rehearsal version of my life involves:
– living in a suburban area with a lot of concrete
– working in an office
– bringing lunch to work
– chit chatting with people about the minutia of daily life
– driving on a lot of highways and sitting in traffic
– paying bills & going to the grocery store

The real / big version of my life has limitless possibilities but involves some things like:
– living in many world-class cities (Paris, Rome, London)
– living in a beautiful, stylish glass condo
– seeing the whole world
– flying on planes & spending time in airports
– hanging around music recording studios
– possibly making movies
– going to the spa & getting massages on a caribbean beach
– doing yoga in India
– talking to people about meaningful & big ideas (getting to the bottom of life’s mysteries)
– working in a creative job where I get to make things when I feel like it & work as much or as little as I want

I’m starting to get concerned about this because I can see a possibility that the real / big life might never happen & also because I’ve heard the phrase “life is not a dress rehearsal” so if I live the rest of my life like this, I think I will end up disappointed in the end.

Do other people out there experience this? – do you feel like you are biding time living in a dress rehearsal and that someday you will be living the real life that you imagine?
