It took a few tries, and I started off easy with the bed making, then building on that. It's not so hard to make yourself make your bed or drink some water. Then when I'd gotten a couple of those down as a regular thing, it was just a bit of reflection - 'well I didn't really feel like making the bed or walking to the kitchen all those days, but now that I do it it doesn't really matter if I want to. I guess eventually push-ups will work the same'

Turns out pretty much everything works the same. Maybe the trick is that I didn't really do anything that wasn't incremental, just a day at a time, but you just kind of keep going with the momentum.

Now I tend to just do that reflexively because it's just worked so many times in so many different areas.
