Patience old chap, patience.
We are not all sitting at the keyboard ready to instantly spring forth with words of wisdom to every request.
I don't like my career and I want to change it.
Welcome to the big bad world, many people have the same view of their world.
Many things are possible, if you have the ambition to make it happen.
"Electrical Officer in the navy", you say. That is a very specific ambition.
Is it possible? I do not know.
I do not know your abilities, I do not know which country you are in*, you do not tell us.
If you are interested in the navy, why not go along to the recruiting office and discuss your ambitions with the people there.
They will be able to tell you what is possible in your countrys navy.
