Bad prioritization: Make an ordered laundry list and intend to make some progress on everything. Easy. Ineffective.
Good prioritization: Use judgment to pick the top 1-3 items we’re going to focus heavily on – an outcome of sound strategy. Agonize over saying no to perfectly good ideas that just aren’t making the cut at this time. Tough. Powerful.
Applies just as well to building good products, planning how to spend time on a holiday, and building a better quality life.
