What is a good and healthy mind for?
Does what you're doing right now help cultivate a good and healthy mind?
If not, what small tweak can you make now so that you can cultivate a good and healthy mind? Will you do it? Can you imagine how much more happier and effective you could be if you only made a small improvement?
If so, how might you do more of this? Can you leave space for more of this to happen in your day? Where would that space be? What keeps you from adding it now?
Discipline your mind through thoughtful and intentional self-reflection.
Then, commit to and do the work to make life better.
Simple as that.
