What is Dream of my life?

Dream of my life - What is the most important thing I want to achieve or own or accomplish in my life., in other words.... what is my dream of life?

In my childhood I used to dream of becoming a scientist. Now I chose to become an Engineer instead of a scientist (because scientist are paid less?)
I am not sure if that is the reason behind why I am an engineer today.
But the point here is, the childhood dream is no longer a dream now and I am not attached to it anymore.
It may be because to become a scientist was not really what I intended.May be  I wanted to do challenging work and innovate something and I wanted to love what I do. I have learnt in these years that there are other job roles where you can do innovative work. May be that could be a reason.
It may seems to me sometimes that I have traded my dream with the money or it may be that I am an engineer now just by chance and I did not put any effort to realize my dream to become a scientist.
Am I just another bloody rat running in the rats race of making money.
Is money everything?
Is this getting me anywhere ?
It is nothing wrong that the dreams change. Everything in life changes. But we should have one or other dream to go after.
So, what is my dream now?
The honest answer to myself is I don't know. I don't have a dream now, but have some goals.
When you say goals, they are not as craved for, as you do for your dreams and the real passion is missing with the goals.
I also have a wish- " To step on Moon  and see Earth from moon's surface :) ". What I hope is, in next 10 year or later,  the space tourism will pick up and I earn enough to afford a ticket.
The passion is missing in me now, I hope I will eventually pick up one in the due course of my life.

PS:  It's just an attempt to find other confused souls :)
Guys, I would love to hear  your similar conflicting emotions on any  thing in your life.
