I want to make my table of contents as if I'm using
\sections throughout my document, as in the following picture:
It's neat and easy to read. However I don't like the way it looks throughout my document; it makes it look rather messy and space consuming as in the following picture: .
I prefer using
\subsection throughout my document, in my opinion it looks much nicer, as in this picture:

How do I make my table of contents behave as if I have used
\section throughout my document, whilst having used only
\subsection, respectively, throughout?
