“Without commitment, you cannot have depth in anything, whether it's a relationship, a business or a hobby.”

“We have to recognise that there cannot be relationships unless there is commitment, unless there is loyalty, unless there is love, patience, persistence.”

“Do you really want to be with someone who doesn't want to be with you anymore?" I have to think that everyone has to ask this question when trying to deal with a failed relationship--whether it's a marriage, a friendship, or even a business partnership. If someone has changed their mind about you--that person no longer laughs at your jokes, no longer likes to hear you sing, is no longer interested in hearing about your day--you should probably take it as a sign that you should be reevaluating your commitment to that relationship and to that person.”

“Love is spiritual. It's about self-sacrifice and commitment. And discipline. You cannot have true love without discipline and respect. When you lose the respect of your spouse, you've lost everything.”

“The relationship between commitment and doubt is by no means an antagonistic one. Commitment is healthiest when it is not without doubt, but in spite of doubt. (p. 21)”

“A telephone is useful for business, but it's not a relationship.”
