“If you weren’t an optimist, it would be impossible to be an architect.”
― Norman Foster
Designing an environment is an act of optimism. Why go through the trouble and expense of changing things if you have no confidence in the future? Conversely, you can’t do a good job at it if you lack the conviction that things will get better. (Ideally, your intervention will help.)
Being optimistic doesn’t mean being naive. Things are hard. There are injustices in the world. There are confusions and obfuscations. Evil and stupidity can (and sometimes do) win the day.
Being optimistic doesn’t mean believing positive thinking is all you need in the face of hardships. That’s not optimism; it’s delusion. Instead, you must cultivate clear seeing and thinking, and be prepared to work. (One of the things you must work at is maintaining clarity of vision and understanding when stupidity and evil are on the rise and actively working against it.)
You have a choice on how to interpret what you perceive around you. Silver linings abound if you know where to look. The pain in your side could be a passing thing or a sign of a serious disease. If it’s the latter, wouldn’t you rather know sooner rather than later so you can do something about it? The pain can be your friend; it can be the first step towards healing.
