The more you’re talking about or thinking about doing something, the less you’re actually doing anything. Sure, there’s a time and a place for thinking and talking, but at the end of the day, the only way to get work done is by doing.
Think about the last time you tried to get into an exercise routine. Or consistently wake up earlier. Or quit smoking. None of those things are complicated, but all of them are hard to accomplish. We don’t fail at them because they’re complicated, we fail at them because we don’t prioritize them and think about them (let alone do them) on a daily basis.
