This motto represents the definition of dedication. I heard it first in regards to high performing athletes - yet, it translates to nearly every field.
This behavior shows excitement, commitment and initiative; it demonstrates passion beyond the bare minimum.
Many variables line-up to create this situation within ourselves. We must choose meaningful goals. We must have freedom to take risks. We must seek growth.
In order to sustain such motivation, you must stoke an insatiable desire to have an impact; regardless of the path you decide to take.
