Is what you're doing now what you always wanted to do growing up?
In a way yes, but maybe in a bigger, more realistic way, no.
I think that from a young age I knew what I wanted from life, and that was freedom, but, I understood that at some point, I will have to find a job.
This truth was undoubtable, but, I did not accept it for myself, instead, I came up with the idea of learning programming so that I could be able to build my own work, my own project, something that I would be able to make a living from. This was my way out of the normal 9-5 career life, this was my way out of spending most of my waking hours in an office working for someone else company.
So I started learning from a young age how to program, for that goal, for the goal of freedom.
What I wanted to do with that freedom was to travel the world, to go to and see places I could only dream of or see in movies. To see cultures, people, to have experiences that I couldn't have while living the normal career life.
At some point, I did find a job as a programmer, so I can say that I am working in the field I wanted to, but other than that, no, I am not doing now what I always wanted to do growing up, unfortunately.
Without meaning to, I put the whole dream life on hold and remained living this career life, the exact thing I was trying to avoid.
I am working on "freeing" myself from it, and I'm sure that sooner or later (probably sooner) I will be free and I will actually live the life I wanted to since I was a kid.
