If you start with 5 push-ups a day, you'll hit your limits fast just increasing push-ups by one a day, so spread out your improvements by increasing in several exercises, adding more if necessary. Not to do all of them at once every day, but ones to switch between daily. I started something like this years ago, and I'm still keeping up on it. If life happens and I have to take a break from it, I restart it later and reduce my goals so that it doesn't seem so bad trying to jump back into a routine I was maximizing earlier.

The key was to make it a habit I do every day, like brushing my teeth. If I've had a bad day and miss doing my "workout routine" (such that it is, I'm no Arnold), it feels weird to miss one and I look forward to doing it the next day. So in that way once you've made it to a certain point it's self-fulfilling.
