As I prepare for my second term as Secretary-General, I am thinking hard about how we can meet the expectations of the millions of people who see the U.N.'s blue flag as a banner of hope. We have to continue our life-saving work in peacekeeping, human rights, development and humanitarian relief. Votes: 3Ban Ki-moon
You are not thinking hard enough if you are sleeping well. And you would have to be unhinged to take on a subject like the French Revolution, or Rembrandt, and not feel some trepidation. There is always the possibility that you will crash and burn, and the whole thing will be a horrible, vulgar, self-indulgent mess. Votes: 3Simon Schama
Anyone who knew Violet well could tell she was thinking hard, because her long hair was tied up in a ribbon to keep it out of her eyes. Violet had a real knack for inventing and building strange devices, so her brain was often filled with images of pulleys, levers, and gears, and she never wanted to be distracted by something as trivial as her hair.

The worst is that the very hardest thinking will not bring thoughts. They must come like good children of God and cry, "Here we are." You expend effort and energy thinking hard. Then, after you have given up, they come sauntering in with their hands in their pockets. If the effort had not been made to open the door, however, who knows when they could have come.

Artists are taught to be humble about their impact, especially in folk music. It's so ingrained that I have a hard time even thinking I had any impact other than what a normal hit song would have. Votes: 2Janis Ian
One reason why it has become harder to promote the beneficial side of emotions such as anger is that the moral vocabulary of good and bad has been replaced by the self-help lexicon of positive and negative thinking. Votes: 2Julian Baggini
On the whole, when the unexpected danger happens to you, you're thinking so fast, you're thinking so hard, every bit of you is alive to 'What should I do?' 'What can I do?' There isn't a lot of time for contemplation. Votes: 2Kate Adie
