Success is a combination of Intention, Effort and Luck.
Intention is ensuring you’re consciously working toward a direction, hypothesis or goal.
Effort is simply giving it your best shot given all the constraints.
And, luck is the universe’s cooperation in your efforts from time to time. It helps to also think about two kinds of luck. The first kind of luck is “dumb luck” – this strikes from time to time and is impossible to influence. The second kind, however, is the kind of luck whose probability increases with thoughtful preparation (i.e. Intention + Effort).
So, in everything you do, focus on the two questions that drive intention and effort – am I consciously moving toward a direction or hypothesis? And, am I doing the best I can in the circumstances?
Then, take a deep breath and let the universe do its thing.
