Doing more of the thing you want to do usually leads to more of what you want to do.
That doesn’t mean I should eat pizza and ice cream everday, of course, but the math adds up soon enough.
Months ago I got back to my running practice. Some days I just couldn’t grind through a three or four mile run.
Sure enough, I wasn’t eating enough to have the energy for those runs, so they always sucked.
Once you start eating to run, running gets easier.
And so now I’ve run 30 miles a week for the past few weeks, and usually hitting 5000′ of elevation along the way.
I’m not the fastest, but I’m probably the only ding dong who runs up and down this dirt road with no guard rail at least once a week.

And this past Sunday I did it twice, because hey, at 48 years old if you’re not challenging yourself, most likely no one else will, either.
