Sure. The one liner is: spend as much of your free time and energy focusing on giving and helping others rather than enriching yourself.

Find ways to delight in the well-being and success of others—all others, everybody you know, everybody in the world. And when you feel that you aren't getting your fair share, that you'll miss out—take a long, long pause, really feel into that emotion, and see if self-centered thinking ends up getting you more of what makes you happy or not.

Mind: this is incredibly difficult. It's nobody's fault if they can't or don't do this. Almost every single meme and conditioned habit that's in you and the culture you live in works against this pattern.

That approach seems compatible with the article's main points. For example, if you drain your energy by not taking care of yourself, you'll likely end up sitting around watching TV instead of helping people.

I agree that it's compatible, and further that taking care of yourself is crucial to being able to effectively help others. The author might agree too, but in that case it's rather peculiar that everything in the article has an egoistic bent to it. Even if it wasn't the author's intention, I think it's worth pointing out that any mention of altruistic behavior is conspicuously absent from the article.
