Achieving your goal may require a lot of sacrifices in the process. That sacrifice may include losing your relationship with your children, your health, and even your soul.
In the venture to accomplish your goal, consider if doing so requires that you forfeit something more precious than attaining the goal itself.
You could come out more discipline, tolerable, couth, or more vile, lonely, treacherous, or a mix of both.
What you become of to realize your dream is more important than realizing your dream.
