Simple, unless you get full-blown OCD like I do over certain ideas. Then everything: exercising, sleep, eating healthy, etc all goes out the window until the obsession reaches its ultimate conclusion.

So no, it's not so simple for some people.

Everything in moderation, even moderation. Sometimes it's good to go balls-deep in to a manic obsession over a problem/task.
