You're missing the most critical part of "security": realize that at the
end of the day, a computer is still a tool to get a job done. If
security gets in the way, it gets disabled, so that ends you up with a
worse situation than what you had before.

The world's most secure computer in the world is powered down, encased
in a solid block of concrete, lying at the bottom of the Challenger

It is also the world's most useless computer.

To be truly security conscious is to realize that "computer security" is
a study of the condition of the human mind (both that of the attacker
and the attacked) rather than an exact science.
