Own Motivational Thoughts
What does "making it your own" mean? It means experimenting with a good thought until you find a way to use it in your own recipe for motivation. For example, suppose you are in a difficult situation and you just don't feel like dealing with it. Then you play around with the idea of opportunity coming from difficulty, and you discover that it pulls you out of your slump to think about yourself in the future, explaining to a friend how you turned the difficult situation to your advantage.
That is making it your own motivational thought. Of course, it might be more motivating to imagine yourself being interviewed someday about how you overcame this difficult time. Whatever kind of thinking works for you is what you should be doing.
