Yes, taking risks takes faith. Exactly this is why it is so important to cultivate our heartful Intuition over our thinking-mind's ego. The ego only sees what lies within the eye. It is short-sighted, seeing only short-term benefit, overlooking long-term variables.
Our heartful Intuition sees what lies without the eye, making it exert long-term acumen as it already takes into account subconscious elemental variables that our ego cannot see.
So, if we want to make sure that our risk will be 100% worth it, we need to cultivate our Intuition! :)
