What is the longest time you ever waited for someone or something?
Why did you wait?
All things can come to mind, but usually the first thing that sporatically comes to you as you read that sentence, is what you truly want or desire at this very point in your existence. Wherever you are--whether you are at home sitting at your desk, pondering the question on your drive home, or simply lying in bed with the question; curling up with it, getting to know it's secrets as you would with a lover.
At that very point, as space and time stand still in your mind, you should consider carefully--hell, PRAY that what you want is worth this running, PRAY that what you're running toward is what you want.
Then ask yourself this: Does it bring you pleasure? Or does it bring you happiness?
Then only in your heart will you know the answer to that question.
