you should occasionally set yourself some big, ambitious goal, a goal that gets you excited, that makes you want to get up in the morning, and where you've developed a confidence in your own mind that you have a chance of achieving that goal
Instead of working back from a goal, work forward from promising situations. This is what most successful people actually do anyway. Flying a glider is a good metaphor here. Because a glider doesn't have an engine, you can't fly into the wind without losing a lot of altitude. If you let yourself get far downwind of good places to land, your options narrow uncomfortably. As a rule you want to stay upwind.
— Paul Graham
The literature on browsing develops a portrait of a complex, open-ended, embodied human experience, rather than the input-output exchange that characterises traditional information retrieval.
Browsing is an iterative process that entails scanning or glimpsing a field of potential resources, and selecting or sampling items for further investigation and evaluation.
Browsing entails movement through a field of resources; Kwasnik stipulates "movement in a connected space". This movement depends in turn on orientation: a knowledge of the "structure and content" of the browsing field
We may browse with or without a goal in mind, and goals may change as the process unfolds.
I begin each day by selecting some action-oriented goals which I hope will advance some broader achievement-oriented goal. For example, if I'm working towards an in-classroom prototype around a set of ideas, I might aim to spend three focused hours fleshing those ideas out in sketches.
This is a natural spot for brief deliberation, but once the day begins, I focus on the actions I've chosen and suppress planning. The rest of the day's work becomes roughly deontological. I give myself permission to be satisfied with the day if I spent three focused hours sketching like I'd planned.
One way to think about a Dynabook is that it is mainly centered about all aspects of user interface design, especially for children, and not just about how to access, learn and use a computer but how to access, learn and use ideas.
