I'm learning more every day that there is a psychology associated with success. It's deeper than the measurable physical effort, we have to be mindful of what narrative the internal monologue is feeding us.
There is value in knowing the difference between taking calculated risks and being careless. Learning to accept the possibility of failure without being fearful of losing.
Our psychological process informs our body on a cellular level. It requires careful curation and discipline. If you aren't sufficiently programing yourself, you are being programmed by outside influences, past events and fear mechanics.
Even with all the good fortune and opportunity, without the right mental alignment, we are not building on solid ground.
