Being intentional with our time, talent, and treasure takes...well, it takes intentionality.
On the other hand, when we're not intentionally making sense of our time, talent, and treasure...well, we're intentionally not being intentional.
A couple points of caution for both parties:
In your practice of intentional living don't strangle the very things and people you're focused on being intentional with.
In your practice of unintentionality: Beware of celebrating the accidents then expecting them all the more. Beware a victim mindset, it's inevitable. Beware bitterness when lack of intention meets a world on purpose. Beware of abusing the compassion of others. Oh, and beware of the inevitable excuses you'll find coming out of your mouth. Be aware of the soul-sucking that comes with this territory.
