When do you use "I have a habit of ___" as opposed to
"i have the habit of _____" ?
How are they different?

How and when would you use them? Think about the differences between 'the" and "a".

Well, that is precisely the problem I have.
Easier examples such as "I have a cat" and "I have the cat"
are intuitive and cause no concern.
But for "a habit of" and "the habit of", I can't for the life of me
feel how they should differ.
I would appreciate it if you would provide an example that can
clearly show for which instance each phrase is used.
