学业和结婚 are not mutually exclusive choices.

"为了它， 你不愿意有任何打扰." is impossible. The world is not a vacuum. The key to a successful life is to manage and maintain the balance among relationship, career and many other things.

Plus, anybody that says marriage is a 打扰 to his/her career, is just using family as an cheap excuse for their poor management skills. If you foresee that as a potential problem, then you really shouldn't get married.
