One reason so few of us achieve what we truly want is that we never direct our focus; we never concentrate our power. Most people dabble their way through life, never deciding to master anything in particular.
Life is pretty simple: You do some stuff. Most fails. Some works. You do more of what works. If it works big, others quickly copy it. Then you do something else. The trick is the doing something else.
Your pain is the breaking of the shell that encloses your understanding, it is the bitter potion by which the physician within you heals your sick-self therefore trust the physician and drink his remedy in silence and tranquility.
