Your stamina depends on your beliefs.
Without knowing who you are, and why you matter, you are not going to have enough stamina for the journey.
Tapping into a higher purpose is key to making life work on a deeper level.
It's not a problem going through life to survive it, but it can be difficult doing something that actually matters.
And, since no money in the world can cure you of the pain of knowing your life is meaningless, you better find your higher purpose sooner rather than later.
