Long time lurker and I'll spare the obligatory, "I'm over 40 and looking for a career change" post.
I've got a good handle on the certs and their potential outcomes, this forum is great for that.

And of course most websites have potential paths dependent on which of their certs you take etc. Cisco, Comptia and Microsoft all have road maps.
My question is primarily for those who started where I am (potentially completely new career change with no formal education in CS). How did you choose the path you did?
I have an interest in networks, somewhat in databases and Linux. But having no prior experience with them I really don't know.
Is this one of those times when you need to take the CCENT to really know if networking is the path you want?
Same goes for database and Linux.
Microsoft certs seem general enough that they would be beneficial either way, same with the entry level Comptia.
So for those of you who didn't know before you started, what did you do?
