The tripod for success…
Intention, Emotion and Logic.
You need logic.
Even when faced with a logically impossible hurdle, one can often break it up into its elements, and explore possibilities.
Emotion makes you see, and often strive for the seemingly impossible. Too much of emotion though, especially in comparison with logic, can delay failure, but rarely avoid it.
And without the right intention, things might begin, but rarely continue much further.
