Finding the tool is often half the battle.

I am interested in details. If you go into anything far enough, you get into the details of it, and people turn out to be interested in what makes things work.

Most of us end up with no more than five or six people who remember us. Teachers have thousands of people who remember them for the rest of their lives.

When there are starving people in the world, it seems wrong that so many of us Americans eat as much for entertainment as for nourishment.

If you don't enjoy getting up and working and finishing your work and sitting down to a meal with family or friends, then the chances are you're not going to be happy. If someone bases his happiness or unhappiness on major events like a great new job, huge amounts of money, a flawlessly happy marriage or a trip to Paris, that person isn't going to be happy much of the time. If, on the other hand, happiness depends on a good breakfast, flowers in the yard, a drink or a nap, then we are more likely to live with quite a bit of happiness.
