Other commenters on this thread have covered OO fairly well. I have one
clarification detail to add.
In procedural code, you spend a lot of time micromanaging:
put that there
blah + quz is bar
In OO code, you tell each object how to handle its data. Then your
actual program just becomes a bunch of requests for objects to talk to
each other. I know, you are thinking that is how your procedural code
works today. But as you program, look at how much time you are telling
the pieces what their jobs are and how much time you spend telling
pieces to do their jobs.
For further knowledge, read the Design Patterns book. It will seem like
obvious, simple ideas you already know. It did for me. It is not until
you start talking to other people that you realize what you learned. I
am currently reading Holub's "On Patterns". He hammers OO ideas home
As Alan Gauld said, OO does not really start to shine until you reach a
certain level of complexity. It takes most people quite a while to
really get into the mindset. Take it slow, get it wrong, do it again (-:
We all have.
