Because people find this attitude so western, and entitled, I would like to propose a slight change. Rather, I will propose some sound bytes, and hopefully somebody else will express the sentiment eloquently.

Learn to love the process, not the results. Find your foe not in achieving success, but in destroying the obstacles. You can't get anywhere if you cannot motivate yourself to go there.

Or something poetic like that. People should probably not assume that they have the right to do what they love. What they should learn is to love what they do.
