Two thought-provoking quotes from Clayton Christensen.
From Forbes:
I’m an optimistic person. But for the first time in my life, with all my problems, I focused more and more on me–and it was depressing, literally. Sometimes I just wanted to quit trying to learn and speak and write again and just go into my basement and build furniture. I learned an important lesson from this. I learned that focusing on my own problems does not bring happiness. God didn’t say, “Okay. For those with problems it’s okay to focus on yourself. And for those who don’t have problems, I want you to focus on helping others.” Even in dire times God does not exempt me from his commandment to focus my life on others, because it transforms hardship to joy.
Another article ends with this powerful quote:
The person I decide to be has to be robust enough that it doesn’t matter what happens in my life… Life will happen to me. But I don’t want what happens in life to determine who Clay Christensen becomes.
