Here's the cliche.
Compared with what we ought to be, we are only half awake… We are making use of only a small part of our possible mental and physical resources.
But even knowing this, why do we hardly push ourselves?
The human individual thus lives usually far within his limits; he possesses powers of various sorts which he habitually fails to use. He energizes below his maximum, and he behaves below his optimum. In elementary faculty, in co-ordination, in power of inhibition and control, in every conceivable way, his life is contracted like the field of vision of an hysteric subject — but with less excuse, for the poor hysteric is diseased, while in the rest of us it is only an inveterate habit — the habit of inferiority to our full self — that is bad.
Habit-forming is critical part of systematic lifehacking. So long as we automate something good in ourselves, we no longer need to exert our finite will power to derive the benefits.
The problem is we're being guilty of forgetting to venture outside of the habit comfort zone.
We are each and all of us to some extent victims of habit-neurosis. We have to admit the wider potential range and the habitually narrow actual use. We live subject to arrest by degrees of fatigue which we have come only from habit to obey. Most of us may learn to push the barrier farther off, and to live in perfect comfort on much higher levels of power.
