In order to grasp every opportunity, you cannot — you must not — decide your "career path" in advance. Don't have a job fixed in your sights and work backwards — it can be the road to disappointment because you risk passing up opportunities that might take you "off-course."

This is what happens when we confuse morality with frugality. We've all been taught that the bake sale with five percent overhead is morally superior to the professional fundraising enterprise with 40 percent overhead, but we're missing the most important piece of information, which is: What is the actual size of these pies? Who cares if the bake sale only has five percent overhead if it's tiny?

I was going to say work on what you love, but that's not really it. It's so easy to convince yourself that you love what you're doing — who wants to admit that they don't? When I think about it, the happiest and most successful people I know don't just love what they do, they're obsessed with solving an important problem, something that matters to them.

I held out for participation in the 1984 election the dictatorship called, even if I knew it would be rigged. I was warned by the lawyers of the opposition that I ran the grave risk of legitimizing the forgone results of elections that were clearly going to be fraudulent. But I was not fighting for lawyers, but for the people in whose intelligence I had implicit faith. By the exercise of democracy, even in a dictatorship, they would be prepared for democracy when it came.

In my opinion, the key to dealing with the future lies in knowing where you are, even if you can't know precisely where you're going. Knowing where you are in a cycle and what that implies for the future is very different from predicting the timing, extent and shape of the next cyclical move.
